[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.

Reinstate "crypto: crct10dif - Wrap crc_t10dif function all to use crypto transform framework" This patch reinstates commits 67822649d7305caf3dd50ed46c27b99c94eff996 39761214eefc6b070f29402aa1165f24d789b3f7 0b95a7f85718adcbba36407ef88bba0a7379ed03 31d939625a9a20b1badd2d4e6bf6fd39fa523405 2d31e518a42828df7877bca23a958627d60408bc Now that module softdeps are in the kernel we can use that to resolve the boot issue which cause the revert.
