Anyway, if this will ever be done on top, it will be enough to call vsp1_entity_destroy() in case of errors as it clears up the control handler already.

Some VSP modules initialize their control handler after initializing the subdev, while some initialize it before. This makes the code inconsistent and more error prone. Standardize on control initialization after initializing the subdev.
