Unfortunately this change broke boot on some systems that used an
initrd which does not include the newly created crct10dif modules.
As these modules are required by sd_mod under certain configurations
this is a serious problem.

Tim Chen 2d31e518a4 crypto: crct10dif - Wrap crc_t10dif function all to use crypto transform framework 
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.

Martin K. Petersen f11f594edb [SCSI] lib: Add support for the T10 (SCSI) Data Integrity Field CRC 
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.
