[PATCH 05/16] ratp: completely ignore RST flagged packets in behavior G

[Aleksander Morgado]

The reference says:

    This procedure represents the behavior of the CLOSED state of a
    connection. All incoming packets are discarded. If the packet
    had the RST flag set take no action. Otherwise it is necessary
    to build a RST packet.

So, skip building the RST packet if the incoming one had RST set.
