scsi: fix sense code for EREMOTEIO

Browse Source 
SENSE_CODE(LUN_COMM_FAILURE) has an ABORTED COMMAND sense key,
so it results in a retry in Linux.  To ensure that EREMOTEIO
is forwarded to the guest, use a HARDWARE ERROR sense key
instead.  Note that the code before commit d7a84021d was incorrect
because it used HARDWARE_ERROR as a SCSI status, not as a sense
key.
