FB fault buffer is enabled on finalize poweron. Disable the buffer in prepare poweroff. This also eliminates the need to disable the buffer in fault info mem destroy which otherwise accesses GPU registers after these are locked in prepare poweroff. Bug 200427479 Change-Id: I1ca3e6ed4417847731c09b887134f215a2ba331c Signed-off-by: Aparna Das <aparnad@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1776387 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
