nvme-tcp: use crc32c() and skb_copy_and_crc32c_datagram_iter()

Browse source

Now that the crc32c() library function directly takes advantage of
architecture-specific optimizations and there also now exists a function
skb_copy_and_crc32c_datagram_iter(), it is unnecessary to go through the
crypto_ahash API.  Just use those functions.  This is much simpler, and
it also improves performance due to eliminating the crypto API overhead.
