[ Upstream commit 664227fde63844d69e9ec9e90a8a7801e6ff072d ]
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.
