quartz/videorenderer: Get rid of hEvent.

This event was at various times used for several different purposes. The only current use is apparently to prevent stale samples from being rendered after IPin::EndFlush() completes, but in practice there's actually no foolproof way to prevent this race in the video renderer. On the other hand, as long as the filter driving the graph can ensure this, there's no need to do so.
