Thanks.

wait_for_init_devices_probe() relaxes ordering rules for all devices
and it's not something we want to do unless we really need it. That's
why we are doing that only if we can't find any network device in the
first iteration.

Even without this change, I'm not sure the wait_for_device_probe()
needs to be within the loop. It's probably sufficient to just do it
once in the beginning, but it's already there and I'm not sure if I'm
missing some scenarios, so I left that part as is.
