netfilter: nf_tables: always initialize flowtable hook list in transaction
The hook list is used if nft_trans_flowtable_update(trans) == true. However, initialize this list for other cases for safety reasons. Fixes: 78d9f48f7f44 ("netfilter: nf_tables: add devices to existing flowtable") Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
