Whenever there is a change in the buffer geometry, set a flag in the gralloc handle stating that the buffer geometry has changed. In the HWC, whenever we encounter an update in the geometry, if the channel is already open, we just call the necessary ioctls to update the overlay information and not unnecessarily open/close channels.
