Shin'ichiro Kawasaki 1849f297f5 scsi-generic: Check sense key before request snooping and patching 
When READ CAPACITY command completes, scsi_read_complete() function
snoops the command result and updates SCSIDevice members blocksize and
max_lba . However, this update is executed even when READ CAPACITY
command indicates an error in sense data. This causes unexpected
blocksize update with zero value for SCSI devices without
READ CAPACITY(10) command support and eventually results in a divide
by zero. An emulated device by TCMU-runner is an example of a device
that doesn't support READ CAPACITY(10) command.

To avoid the unexpected update, add sense key check in
scsi_read_complete() function. The function already checks the sense key
for VPD Block Limits emulation. Do the scsi_parse_sense_buf() call for
all requests rather than just for VPD Block Limits emulation, so that
blocksize and max_lba are only updated if READ CAPACITY returns zero
sense key.
