netfilter: nft_ct: track register operations

Check if the destination register already contains the data that this ct
expression performs. This allows to skip this redundant operation. If
the destination contains a different selector, update the register
tracking information.

Export nft_expr_reduce_bitwise as a symbol since nft_ct might be
compiled as a module.
