From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>
Currently object size is returned for the rotated VMA size which can be
bigger than the rotated view itself. Since the binding code pads all
excess size with scratch pages the only minor issue with this is wasting
some GGTT space, but still feels nicer to fix and report the real size.
