mgw: Find and store RTP conn local_addr once during CRCX handling
It doesn't make sense to call the function several times since anyway we
are only binding during
allocate_port()->mgcp_bind_net_rtp_port()->bind_rtp()->mgcp_create_bind()->osmo_sock_init2().
Let's better calculate the local IP addr once and use that stored value.
THis is a previous step towards next commit updating the local IP addr
and re-bindng if encessary.
