    wacom: Avoid poking disposed object
    
    A little above in the function, we update the page UI, maybe destroying
    the bits that allow decoupling display-attached tablets from their display.
    Later on, we unconditionally update the its switch.
    
    This can't bode well on tablets where the widget was already destroyed.
