Guillaume Nault a0fd6e8759 l2tp: hold tunnel used while creating sessions with netlink ...

commit e702c1204e upstream.

Use l2tp_tunnel_get() to retrieve tunnel, so that it can't go away on
us. Otherwise l2tp_tunnel_destruct() might release the last reference
count concurrently, thus freeing the tunnel while we're using it.
