Commit a818a4b changed scsi_bus_legacy_handle_cmdline() to report
errors from scsi_bus_legacy_add_drive() with error_report() in
addition to returning them. That's inappropriate.
Two kinds of callers:
1. realize methods (devices "esp", "virtio-scsi-device" and
"spapr-vscsi")
The error object gets passed up the call chain until it gets
reported again and freed.
Example:
$ qemu-system-arm -M virt -S -display none \
> -drive if=scsi,id=foo,bus=1,file=tmp.qcow2 \
> -device nec-usb-xhci -device usb-storage,drive=foo \
> -device virtio-scsi-pci
qemu-system-arm: -drive if=scsi,id=foo,bus=1,file=tmp.qcow2: Property 'scsi-disk.drive' can't take value 'foo', it's in use
qemu-system-arm: -drive if=scsi,id=foo,bus=1,file=tmp.qcow2: Setting drive property failed
qemu-system-arm: -device virtio-scsi-pci: Setting drive property failed
qemu-system-arm: -device virtio-scsi-pci: Device initialization failed
qemu-system-arm: -device virtio-scsi-pci: Device 'virtio-scsi-pci' could not be initialized
The second message in this error cascade comes from
scsi_bus_legacy_handle_cmdline(). The error object then gets
passed up to the qdev_init() called from
virtio_scsi_pci_init_pci(), which reports it again.
2. init methods (devices "am53c974", "dc390", "lsi53c895a",
"lsi53c810", "megasas", "megasas-gen2")
init methods need to report their errors with qerror_report().
These don't. The inappropriate error_report() papers over the bug.
error_report() isn't the same as qerror_report() in QMP context,
but this can't actually happen: QMP can still only hot-plug, and
callers call scsi_bus_legacy_handle_cmdline() only on cold-plug.
Except for sysbus_esp_realize(), but that can't be hot-plugged at
all, as far as I can tell.
Fix the init methods and drop the inappropriate error_report() in
scsi_bus_legacy_handle_cmdline().

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).

Replace "init/destroy" with "realize/unrealize" in SCSIDeviceClass,
which has errp as a parameter. So all the implementations now use
error_setg instead of error_report for reporting error.
Also in scsi_bus_legacy_handle_cmdline, report the error when
initializing the if=scsi devices, before returning it, because in the
callee, error_report is changed to error_setg. And the callers don't
have the right locations (e.g. "-drive if=scsi").

After previous Peter patch, they are redundant. This way we don't
assign them except when needed. Once there, there were lots of case
where the ".fields" indentation was wrong:
.fields = (VMStateField []) {
and
.fields = (VMStateField []) {
Change all the combinations to:
.fields = (VMStateField[]){
The biggest problem (appart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

Currently, treat it exactly as a 53C895A.
53C895A is a 53C810 with more capabilities, so this should work.
However, this lets us test different code paths on Linux, which
don't use lastest features if it detect a 810, or on some OSes
which only support 810 and not 895A (like very old Windows NT
versions).

53C895A datasheet says that this register is read/write, and that the value
returned on read access is dependant of DMA FIFO state. However, nothing is
said for written value.
53C810A datasheet gives more insight about this register:
"This was a general purpose read/write register in previous SYM53C8XX
family chips. Although it is still a read/write register, Symbios reserves
the right to use these bits for future 53C8XX family enhancements."
This prevents going to the default case, which prints an error message.
