Retire all requests if we resort to wedged the driver on suspend. They

Or given that parking is now sync it could work to make
intel_gt_park_requests flush and then intel_gt_pm_wait_for_idle would
handle it. But that would keep the GPU alive for too long, given that
request retire can run independently. So perhaps this is better.
