    wacom: Avoid infinite recursion in gsettings callback
    
    On a tablet PC, EDID matching will fail as the monitor is not
    from Wacom and heuristic matching will be used instead in
    find_output().
    
    find_output() will then write the results in gsettings which
    can cause an infinite recursion since find_output() is being
    called (indirectly) from the gsettings callback in g-s-d.
    
    To avoid this, remove the call to set_display_by_output() in
    find_output().
