bugfix CU/DU: use correct IP address for GTP-U

Browse Source 
Not only the teid is received from the DU but also the IP address. We
have to use it too.

Also, don't connect the UDP socket. The parameter remote_s_address in the
configuration file must not be used, at least not for gtp-u because the
IP address is received from the DU (plus for later, for multiple DUs, it
won't work at all).
