l2tp: initialise session's refcount before making it reachable

Sessions must be fully initialised before calling
l2tp_session_add_to_tunnel(). Otherwise, there's a short time frame
where partially initialised sessions can be accessed by external users.

Fixes: dbdbc73b4478 ("l2tp: fix duplicate session creation")
