Ouch, I accidentally pushed the previous change without running the
tests:
- we need to check, in conf_ports(), that udp_sock_init()
managed to bind at least a port, not the opposite
- for -T and -U, we have no way to know if we'll manage to bind
the port later, so never report an error for those
Fixes: 3d0de2c1d727 ("conf, tcp, udp: Exit if we fail to bind sockets for all given ports")
