l2tp: hold session while sending creation notifications

Browse source

commit 5e6a9e5a35 upstream.

l2tp_session_find() doesn't take any reference on the returned session.
Therefore, the session may disappear while sending the notification.

Use l2tp_session_get() instead and decrement session's refcount once
the notification is sent.

Fixes: 33f72e6f0c ("l2tp : multicast notification to the registered listeners")
