[Intel-gfx] [CI 3/3] drm/i915: Mark the removal of the i915_request from the sched.link

[Chris Wilson]

Keep the rq->fence.flags consistent with the status of the
rq->sched.link, and clear the associated bits when decoupling the link
on retirement (as we may wish to inspect those flags independent of
other state).

Fixes: 32ff621fd744 ("drm/i915/gt: Allow temporary suspension of inflight requests")
