drm/i915: Propagate errors on awaiting already signaled dma-fences

Browse source

If we see an already signaled dma-fence that we want to await on, we skip
adding to the i915_sw_fence. However, we should pay attention to whether
there was an error on that fence and if so propagate it for our future
request.
