Christoph Hellwig e54b064cb2 nvme: move the dying queue check from cancel to completion ... With multipath we don't want a hard DNR bit on a request that is cancelled by a controller reset, but instead want to be able to retry it on another patch. To archive this don't always set the DNR bit when the queue is dying in nvme_cancel_request, but defer that decision to nvme_req_needs_retry. Note that it applies to any command there and not just cancelled commands, but one the queue is dying that is the right thing to do anyway.
