> Previously it was possible to increment `processed_jobs` to a value greater than
> requested `nb_ops`, because after flushing at most `nb_ops` jobs the while loop
> continued, so `processed_jobs` could still be incremented and it was possible for
> this variable to be greater than `nb_ops`. If `ops` provided to the function were
> only `nb_ops` long, then the `aesni_mb_dequeue_burst()` would write to the
> memory outside of `ops` array.
