network: do not patch PT of RTCP packets
At the moment all packets that are sent with mgcp_send are fed into
mgcp_patch_pt(). This functions corrects the payload type so that it
matches the codec configuration on the egress side. However, this
functions is only to be used with RTP packets and must not be used on
RTCP packets, which we currently do because we do not check if the
packet is RTCP or RTP.
- Check if the packet is RTP before running mgcp_patch_pt()
