netfilter: nf_tables: Eliminate duplicated code in nf_tables_table_enable()
If something fails in nf_tables_table_enable(), it unregisters the chains. But the rollback code is the same as nf_tables_table_disable() almostly, except there is one counter check. Now create one wrapper function to eliminate the duplicated codes. Signed-off-by: Feng <fgao@ikuai8.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
