Now that module softdeps are in the kernel we can use that to resolve
the boot issue which cause the revert.

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 31d939625a crypto: crct10dif - Accelerated CRC T10 DIF computation with PCLMULQDQ instruction 
This is the x86_64 CRC T10 DIF transform accelerated with the PCLMULQDQ
instructions.  Details discussing the implementation can be found in the
paper:

"Fast CRC Computation for Generic Polynomials Using PCLMULQDQ Instruction"
