    ikev2 nat: simplify if() guarding nat_traversal_change_port_lookup() call; document why it is broken
    In IKEv2 when a secured request with a changed sender is received
    by a responder that is not behind a NAT then the remote port
    should be updated.  The code trying to do this is broken:
    - state isn't sufficient as either end can initiate an exchange
    - can't assume that the very original IKE SA responder isn't behind
      a NAT
