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.
