Currently, after enqueue_burst, there may be ops_unused ops left for next round enqueue. And in next round preparation, only ops_needed ops will be added. But if in the final round the left ops is less than ops_needed, there will be invalid ops between the new needed ops and previous unused ops. The previous unused ops should be moved front after the needed ops.
In the commit[1], an resubmission fix was added to throughput test, and the fix was missed for verify. This commit adds the missed resubmission fix for verify.
