[Intel-gfx] [PATCH 06/28] drm/i915: Protect our local workers against I915_FENCE_TIMEOUT

[Chris Wilson]

Trust our own workers to not cause unnecessary delays and disable the
automatic timeout on their asynchronous fence waits. (Along the same
lines that we trust our own requests to complete eventually, if
necessary by force.)
