The Rx path may grab the socket right before pppol2tp_release(), but nothing guarantees that it will enqueue packets before skb_queue_purge(). Therefore, the socket can be destroyed without its queues fully purged.
Fix this by purging queues in pppol2tp_session_destruct() where we're guaranteed nothing is still referencing the socket.
