HID: wacom: fix problems when device is not a valid USB device
commit 720ac467204a70308bd687927ed475afb904e11b upstream.
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.
