drm/i915: Don't cancel DRRS worker synchronously for flush/invalidate
It's not needed since the worker rechecks that it didn't race. We only
need to cancel synchronously after disabling drrs to make sure the
worker really is gone (e.g. for driver unload). But for normal
operation the stall is just wasted time.
