nft: Support nft_is_table_compatible() per chain

When operating on a single chain only, compatibility checking causes
unwanted overhead by checking all chains of the current table. Avoid
this by accepting the current chain name as parameter and pass it along
to nft_chain_list_get().

While being at it, introduce nft_assert_table_compatible() which
calls xtables_error() in case compatibility check fails. If a chain name
was given, include that in error message.
