This avoids assigning frame tracking data to buffers that will be returned early, such as when a source resolution change is detected. Protect the destination buffer state update with the hardware spinlock so the completion path observes a consistent context and frame number. Stop walking the done queue after completing the next expected frame, since the remaining buffers still need to wait for their own frame order.
