Subject: [PATCH v2 6/6] HID: uclogic: actually invert the in-range bit for huion tablets only

This hack is only needed for Huion tablets. It does not seem to have
any effect on the other tablets handled by this device right now, but
it's better to check for the product id sooner than discovering that
we have messed up one tablet later.
