input: Avoid creating the PAD device multiple times

Browse source 
If a pad device for a tablet exists, reloading the configuration,
removing/reading the device or even suspending the system will recreate
the same Wayland input device multiple times.

Make sure we don't re-create the same Wayland device more than
necessary.
