lib/crc64-rocksoft: stop wrapping the crypto API
Following what was done for the CRC32 and CRC-T10DIF library functions,
get rid of the pointless use of the crypto API and make
crc64_rocksoft_update() call into the library directly. This is faster
and simpler.
Remove crc64_rocksoft() (the version of the function that did not take a
'crc' argument) since it is unused.
