Looks like there is a bug here. We don't need to enqueue operations back in the
ring here.
We used to enqueue in the ring when crypto processing was done in enqueue, but
now this is part of dequeue
and we already dequeued the operations from the ring.
As far as I know, the only enqueue operation in the ring should be done in
enqueue_burst.
Thanks,
Pablo
