[SCSI] don't reference freed command in scsi_prep_return
Patch
commit 0479633686d370303e3430256ace4bd5f7f138dc

[SCSI] do not manipulate device reference counts in scsi_get/put_command
Introduced a use after free:I in the kill case of scsi_prep_return we have to
release our device reference, but we do this trying to reference the just
freed command. Use the local sdev pointer instead.
