Let's kill this legacy iand almost unused rq_enabled version
in favor of the real one that is checked at
intel_irqs_enabled().

The commit 'ac1723c16b66 ("drm/i915: Track IRQ state
in local device state")' shows that this was a legacy
DRM level irq_enabled information that got removed.

But the driver one already existed under a different
name.

But the driver has already one under a different name (and
perhaps specify which one and which location :-))

I don't think you need to send a v2 for commit log changes.

I think we should just stick a

	if (drm_WARN_ON(&dev_priv->drm, !dev_priv->runtime_pm.irqs_enabled))

here and remove the FIXME. I don't see a path like that anywhere,
anymore.
