    kernel - Fix syncache vs close(listen_socket) race
    
    * Attempt to fix a race where a listen socket is closed with an active
      syncache.  The tcpcb is detached prior to the syncache being destroyed
      resulting in a race where a new incoming connection can complete and
      attempt to dive the listen socket's tcpcb.
    
    * Detach the tcpcb after the syncache is destroyed rather than before.
