mgcp: Avoid crashing when rtpmap is not complete

The NAT sends an incomplete SDP file for the purpose of informing
the BSC about the remote IP/PORT early. The case of an incomplete
SDP file was not considered. Check if there is a codec and if not
skip it.

TODO: We need to have a better end-point life cycle test.
