    wayland: Unset window_impl->commit_pending when hiding the surface
    
    A surface may be hidden when a frame is already scheduled, which may cause
    crashes on on_frame_clock_after_paint() when calling commit() on a NULL
    surface. To fix this, ensure commit_pending is also set to FALSE when the
    surface is gone.
