It's not directly in cryptd because it uses the helpers from algapi.c. In particular ablkcipher_enqueue_request has the necessary logic to handle this correctly. You could either use that helper yourself once your hardware queue fills up, or implement your own backlog logic. The key is each tfm object must be guaranteed to be able to queue at least one request.
