Nicolas Dufresne	ea08442699	codecalphademux: Fix handling of flow combine ... As the alphacombine is simplified to received matching pair of buffers, we can't just stop streaming when we receive EOS from downstream. Due to usage of queue, the moment we get this return value may differ. Though, by continuing pushing, we override the last_flowret on the pad which can make us miss that we effectively can combine all flow into EOS.
