HID: wacom: fix problems when device is not a valid USB device
The wacom driver accepts devices of more than just USB types, but some
code paths can cause problems if the device being controlled is not a
USB device due to a lack of checking. Add the needed checks to ensure
that the USB device accesses are only happening on a "real" USB device,
and not one on some other bus.
