    testing: tweak TCP tests to match current debug output

    tcp: off-load closing the tcp port
    Instead of trying to delete the TCP event handler while in the TCP
    event handler, do it using a dedicated callback.
    - sending ff (aka keepalive) triggers two callbacks (an error then
      0-bytes aka EOF regardless of any attempt to delete the callback)
      Accept this and schedule a callback to run after the events have
      been drained.
    - because .st_interface references aren't counted, there's a race
      between the TCP code seeing a socket error and the TCP IKE SA being
      Extend the IKETCP state machine to handle this case.
    This change is more conservative then making .st_interface reference
