    tcp: stop doing superfluous work after sending RST

    When sending a RST control segment in tcp_output() it
    means we are in TCPS_CLOSED state, called from tcp_drop().
    Once the RST is sent, don't call tcp_timer_activate() or
    update anything in tcpcb, since that will go away shortly.
