    gdk/quartz: Fix mixup in attributes usage creating window implementation
    
    First, attributes can be NULL (which is always the case when calling
    gdk_window_ensure_native) so do not unconditionally dereference it.
    
    Then the window_type should be taken directly from the GdkWindow as
    in other backends (such as the X11 one for example).
