[nft PATCH v4 27/32] netlink: rename bitwise operation functions

[Jeremy Sowden <jeremy@azazel.net>]

In the next few patches we add support for doing AND, OR and XOR
operations directly in the kernel, so rename a couple of functions and
an enum constant related to mask-and-xor boolean operations.
