The DU driver handles non-visible planes (fully clipped by the display's boundaries) by considering them as disabled. It thus disables the plane at the hardware level when the plane if moved off-screen. However, if the plane was previously disabled and is non-visible when it gets enabled, the attempt to disable it crashes, ad the plane wasn't previously enabled. Fix it.
