Close socket request will abort tcp write/connect

Browse Source 
When tcp write/connect is running, close socket request will abort
    it and continue to delete netconn and close tcp. Do not immediately
    return after aborting tcp write/connect. Otherwise, tcp close
    requeset will block and tcp write/connect will crash.
