The reason for the indirection was to not bypass the abstraction
nft_data_cmp() provides.

No objection to the change but maybe leave a comment in
nft_data_cmp() that if one changes nft_data_cmp() one needs to
look at nft_hash and see if the direct use of rhashtable_lookup()
is still valid.

Copying Patrick as well.
