    drm/i915: Drain the device workqueue on unload

    Workers on the i915->wq may rearm themselves so for completeness we need
    to replace our flush_workqueue() with a call to drain_workqueue() before
    unloading the device.

    v2: Reinforce the drain_workqueue with an preceding rcu_barrier() as a
    few of the tasks that need to be drained may first be armed by RCU.

Should fix it in the short term. Reusing i915_gem_suspend() can hopefully be
done at leisure.
