GTP,UE addrs in osmo_sockaddr: assert( port == 0 )

Assert that all port numbers in osmo_sockaddr parts of up_gtp_action are
zero: uncover code paths that leak port numbers into the gtp_action API.

GTP and UE addresses have no port information. Port numbers in GTP,UE
addresses stored in struct osmo_sockaddr should be zero, so that
- to-string conversion via osmo_sockaddr_to_str_c() returns only an IP
  address: for nftables rules and logging.
- osmo_sockaddr_cmp() matches on identical IP addresses "only", without
  the port numbers causing mismatches: for finding tunnels and devs.
