mgcp_network: do not deliver RTP packets with unpatched PT

When a call leg is set up, then the call agent (e.g. BSC, MSC, etc.)
will also negotiate a codec along with a payload type number. When
sending RTP packets, each RTP packet must also contain the negotiated
payload type number. To prevent the emission of RTP packets with an
incorrect payload type number, ensure that no packet is sent when
mgcp_patch_pt() fails.
