[SCSI] sd: Support disks formatted with DIF Type 2
Disks formatted with DIF Type 2 reject READ/WRITE 6/10/12/16 commands
when protection is enabled. Only the 32-byte variants are supported.
Implement support for issusing 32-byte READ/WRITE and enable Type 2
drives in the protection type detection logic.
