Re: [PATCH -next] crct10dif: remove extra function call in crc_t10dif() and crc_t10dif_update()

Calling crypto_shash_import() in crc_t10dif() and crc_t10dif_update()
is overkill as the existing crct10dif modules (crct10dif-generic and
crct10dif-pclmul) don't require.

We also do the same thing with crc32c() in lib/libcrc32.c.
