nvme-tcp: don't update queue count when failing to set io queues
We update ctrl->queue_count and schedule another reconnect when io queue count is zero.But we will never try to create any io queue in next reco- nnection, because ctrl->queue_count already set to zero.We will end up having an admin-only session in Live state, which is exactly what we try to avoid in the original patch. Update ctrl->queue_count after queue_count zero checking to fix it. Signed-off-by: Ruozhu Li <liruozhu@huawei.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
