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

+ For x86_64 processors with SSE4.2 and PCLMULQDQ supported,
+ CRC T10 DIF PCLMULQDQ computation can be hardware
+ accelerated PCLMULQDQ instruction. This option will create
+ 'crct10dif-plcmul' module, which is faster when computing the
