scsi: restructure command initialization for TYPE_FS requests
We should call the device handler prep_fn for all TYPE_FS requests, not just simple read/write calls that are handled by the disk driver. Restructure the common I/O code to call the prep_fn handler and zero out the CDB, and just leave the call to scsi_init_io to the ULDs.
