[Qemu-devel] [PATCH] SCSI: Update the sense code for PREVENT REMOVAL errors

[Ronnie Sahlberg <ronniesahlberg@gmail.com>]

Change the sense codes for failures to eject a device that is locked
by PREVENT_ALLOW_MEDIUM_REMOVAL from
the generic MEDIA_LOAD_OR_EJECT_FAILED to the more specific
MEDIUM_REMOVAL_PREVENTED.

The second sense code is more accurate, and is also listed in MMC annex F
for the recommended sense codes for MMC devices while the first sense code is not.
