l2tp: fix pseudo-wire type for sessions created by pppol2tp_connect()
Define cfg.pw_type so that the new session is created with its .pwtype field properly set (L2TP_PWTYPE_PPP). Not setting the pseudo-wire type had several annoying effects: * Invalid value returned in the L2TP_ATTR_PW_TYPE attribute when dumping sessions with the netlink API. * Impossibility to delete the session using the netlink API (because l2tp_nl_cmd_session_delete() gets the deletion callback function from an array indexed by the session's pseudo-wire type). Also, there are several cases where we should check a session's pseudo-wire type. For example, pppol2tp_connect() should refuse to connect a session that is not PPPoL2TP, but that requires the session's .pwtype field to be properly set.
