 Log Message:
 wg(4): Process all altq'd packets when deleting peer.
 
 Can't just drop them because we can only go through all packets on an
 interface at a time, for all peers -- so we'd either have to drop all
 peers' packets, or requeue the packets for other peers.  Probably not
 worth the trouble, so let's just wait for all the packets currently
 queued up to go through first.
 
 This requires reordering teardown so that we wg_destroy_all_peers,
 and thus wg_purge_pending_packets, _before_ we wg_if_detach, because
 wg_if_detach -> if_detach destroys the lock that IFQ_DEQUEUE uses.
