When CRC T10 DIF is calculated using the crypto transform framework, we
wrap the crc_t10dif function call to utilize it. This allows us to
take advantage of any accelerated CRC T10 DIF transform that is
plugged into the crypto framework.

The SCSI Block Protocol uses this 16-bit CRC to verify the integrity
of each data sector. crc_t10dif() is used by sd_dif.c when performing
I/O to or from disks formatted with protection information.
