During CQE error recovery, error-free data commands get requeued if there is any data left to transfer, but non-data commands are completed even though they have not been processed. Requeue them instead. Note the only non-data command is cache flush, which would have resulted in a cache flush being lost if it was queued at the time of CQE recovery.
