drm: don't unnecessarily enable the polling work
... by properly checking connector->polled. This doesn't matter too much because the polling work itself gets this slightly more right and doesn't set repoll if there's nothing to do. But we can do better. v2: Chris Wilson noticed that I broke polling, since repoll will never ever be set true. Fix this up, and simplify the logic a bit while at it.
