Chris Wilson dc58958d08 drm/i915: Assert the local engine->wakeref is active
Due to the asynchronous tasklet and recursive GT wakeref, it may happen
that we submit to the engine (underneath it's own wakeref) prior to the
central wakeref being marked as taken. Switch to checking the local wakeref
for greater consistency.
