[SCSI] sd: Detach DIF from block integrity infrastructure
So far we have only issued DIF commands if CONFIG_BLK_DEV_INTEGRITY is
enabled. However, communication between initiator and target should be
independent of protection information DMA. There are DIF-only host
adapters coming out that will be able to take advantage of this.
Move the relevant DIF bits to sd.c.
