netfilter: expect: add to hash table after expect init assuming we have lockless readers we should make sure they can only see expectations that have already been initialized. hlist_add_head_rcu acts as memory barrier, move it after timer setup. Theoretically we could crash due to a del_timer() on other cpu seeing garbage data. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
