scsi-disk: return CHECK CONDITION for unknown page codes in the MODE SENSE command
SCSI-Spec:
http://ldkelley.com/SCSI2/SCSI2/SCSI2-08.html#8.2.10
"An initiator may request any one or all of the supported mode pages
from a target. If an initiator issues a MODE SENSE command with a
page code value not implemented by the target, the target shall return
CHECK CONDITION status and shall set the sense key to ILLEGAL REQUEST
and the additional sense code to INVALID FIELD IN CDB."
