udev: Fix device matching in the accelerometer

Browse Source 
As we were searching by ID_PATH, it would have been possible
for us to find a sibling device instead of the device we were
looking for.

This fixes device matching on the WeTab with the upstream kernel,
as it was trying to use the "Asus Laptop extra buttons" device
instead of the accelerometer.
