l2tp: only accept PPP sessions in pppol2tp_connect()
l2tp_session_priv() returns a struct pppol2tp_session pointer only for
PPPoL2TP sessions. In particular, if the session is an L2TP_PWTYPE_ETH
pseudo-wire, l2tp_session_priv() returns a pointer to an l2tp_eth_sess
structure, which is much smaller than struct pppol2tp_session. This
leads to invalid memory dereference when trying to lock ps->sk_lock.
Fixes: d9e31d17ceba ("l2tp: Add L2TP ethernet pseudowire support")
