block/file-posix: add bdrv_attach_aio_context callback for host dev and cdrom

Browse Source 
In ed6e2161 ("linux-aio: properly bubble up errors from initialzation"),
I only added a bdrv_attach_aio_context callback for the bdrv_file
driver. There are several other drivers that use the shared
aio_plug callback, though, and they will trip the assertion added to
aio_get_linux_aio because they did not call aio_setup_linux_aio first.
Add the appropriate callback definition to the affected driver
definitions.

Fixes: ed6e2161 ("linux-aio: properly bubble up errors from initialization")
