netfilter: nft_cmp: optimize comparison for 16-bytes

[ Upstream commit 23f68d462984bfda47c7bf663dca347e8e3df549 ]

Allow up to 16-byte comparisons with a new cmp fast version. Use two
64-bit words and calculate the mask representing the bits to be
compared. Make sure the comparison is 64-bit aligned and avoid
out-of-bound memory access on registers.
