Eric Dumazet 485f382f2c l2tp: use rcu_dereference_sk_user_data() in l2tp_udp_encap_recv() ...

[ Upstream commit c1c4772178 ]

Canonical way to fetch sk_user_data from an encap_rcv() handler called
from UDP stack in rcu protected section is to use rcu_dereference_sk_user_data(),
otherwise compiler might read it multiple times.
