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.
