l2tp: use skb_queue_purge in l2tp_ip_destroy_sock
Recent commit ed8ebee6def7 ("l2tp: have l2tp_ip_destroy_sock use
ip_flush_pending_frames") was incorrect in that l2tp_ip does not use
socket cork and ip_flush_pending_frames is for sockets that do. Use
__skb_queue_purge instead and remove the unnecessary lock.
Also unexport ip_flush_pending_frames since it was originally exported
in commit 4ff8863419cd ("ipv4: export ip_flush_pending_frames") for
l2tp and is not used by other modules.
