By default, io_uring will stop submitting a batch of requests if we run into an error submitting a request. This isn't strictly necessary, as the error result is passed out-of-band via a CQE anyway. And it can be a bit confusing for some applications. Provide a way to setup a ring that will continue submitting on error, when the error CQE has been posted. There's still one case that will break out of submission. If we fail allocating a request, then we'll still return -ENOMEM. We could in theory post a CQE for that condition too even if we never got a request. Leave that for a potential followup.
