l2tp: hold tunnel used while creating sessions with netlink
commit e702c1204eb57788ef189c839c8c779368267d70 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.
Fixes: 309795f4bec2 ("l2tp: Add netlink control API for L2TP")
