[PATCH] scsi: add conversion from ENODEV to sense

[Paolo Bonzini]

This is mostly for completeness; I noticed it because ENODEV is used internally
within scsi-disk.c, but when scsi_sense_from_errno(ENODEV) is called the 
resulting
sense is never used and instead scsi_sense_from_host_status() is called later
by scsi_req_complete_failed().
