drm/i915: Skip idling an idle engine During suspend (or module unload), if we have never accessed the engine (i.e. userspace never submitted a batch to it), the engine is idle. Then we attempt to idle the engine by forcing it to the default context, which actually means we submit a render batch to setup the golden context state and then wait for it to complete. We can skip this entirely as we know the engine is idle. v2: Drop incorrect comment.
