lib/crc-t10dif: stop wrapping the crypto API
In preparation for making the CRC-T10DIF library directly optimized for
each architecture, like what has been done for CRC32, get rid of the
weird layering where crc_t10dif_update() calls into the crypto API.
Instead, move crc_t10dif_generic() into the crc-t10dif library module,
and make crc_t10dif_update() just call crc_t10dif_generic().
Acceleration will be reintroduced via crc_t10dif_arch() in the following
patches.
