Not checking return value >=0 from get_udp_socket(...) from util_sockets.c

[kwilsonpdx]

As an example in flight-rnh:

// Set up sockets 157 battery_socket = get_udp_socket(RNH_BATTERY_ADDR); 158 port_socket = get_udp_socket(RNH_PORT_ADDR);

int get_udp_socket(const struct sockaddr *addr);

get_udp_socket returns a -1 or -2 depending on the error. Maybe get_udp_socket should have an error pointer in the argument list?
