netfilter: nfnetlink_log: validate dependencies to avoid breaking atomicity
Check that dependencies are fulfilled before updating the logger
instance, otherwise we can leave things in intermediate state on errors
in nfulnl_recv_config().
[ Ken-ichirou reports that this is also fixing missing instance refcnt drop
on error introduced in his patch 914eebf2f434 ("netfilter: nfnetlink_log:
autoload nf_conntrack_netlink module NFQA_CFG_F_CONNTRACK config flag"). ]
