Streaming and the commit block job only want to apply throttling when they actually copied data instead of skipping it, so they made the calculation of delay_ns conditional. However, delay_ns isn't reset when skipping some sectors, so instead of not waiting, the old delay is applied again.
Properly reset delay_ns where needed.
