Subject: [PATCH] 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")
