[PATCH 16/16] ratp: user close may happen in SYN-RECEIVED state

[Aleksander Morgado <aleksander@aleksander.es>]

The reference says:

     5.2.3. SYN-RECEIVED
     ...
     Departures
       - A CLOSE request is made by the user.  Create a packet with
         FIN set.  Send it and go to the FIN-WAIT state.

Add this missing step.
