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.
