Martin K. Petersen 5db524bd46 [SCSI] sd: Correctly handle 6-byte commands with DIX ...

DIF does not work with 6-byte commands so we previously ignored those
commands when preparing a request.  However, DIX does not need
RDPROTECT/WRPROTECT to be set and 6-byte commands are consequently
perfectly valid in host-only mode.

This patch fixes a problem where we would set the wrong DIX operation
when issuing commands to a legacy disk.
