Carlos Garnacho 0d9c742127 padOsd: Ensure to pick pad devices only
If the underlying X11 input driver creates multiple devices from a single
device node, we may end up picking up the wrong device. So, instead of
picking the first device based on node and bailing out if it's not a pad,
pick the first pad that has that device node, and bail out if there is
none.
