l2tp: don't close sessions in l2tp_tunnel_destruct()
Sessions are already removed by the proto ->destroy() handlers, and since commit f3c66d4e ("l2tp: prevent creation of sessions on terminated tunnels"), we're guaranteed that no new session can be created afterwards. Furthermore, l2tp_tunnel_closeall() can sleep when there are sessions left to close. So we really shouldn't call it in a ->sk_destruct() handler, as it can be used from atomic context.
