l2tp: hold tunnel socket when handling control frames in l2tp_ip and l2tp_ip6
commit 94d7ee0baa8b764cf64ad91ed69464c1a6a0066b upstream.
The code following l2tp_tunnel_find() expects that a new reference is
held on sk. Either sk_receive_skb() or the discard_put error path will
drop a reference from the tunnel's socket.
This issue exists in both l2tp_ip and l2tp_ip6.
Fixes: a3c18422a4b4 ("l2tp: hold socket before dropping lock in l2tp_ip{, 6}_recv()")
