    wayland: do not generate motion events
    
    Mutter generates a motion event for every button and scroll events,
    which confuses Xwayland apps that rely on XMotionEvents for various
    purposes, e.g. it fools rxvt jumpy mouse detection code.
    
    Remove the call to notify_motion() from the button and scroll event
    handlers to avoid these spurious motion events.
