drm/i915: Signal fence completion from i915_request_wait

Browse Source 
With the upcoming change to automanaged i915_active, the intent is that
whenever we wait on the set of active fences, they are signaled and
collected.  The requirement is that all successful returns from
i915_request_wait() signal the fence, so fixup the one remaining path
where we may return before the interrupt has been run.
