udevd: do not wrongly delay events for devices with swapped names

Renaming network devices might delay events for the other device, which has
the same devpath in the meantime as the original event. Causing a delay until
the timout of the event is reached.

Look at the ifindex/devnum of the devices to check if they are really
the same devices.
