That meant the chardev couldn't be re-used. Also, since chardev hot-plug isn't possible so far, this means virtio-console hot-plug isn't feasible as well. With this change, the chardev is kept around. A new virtio-console channel can then be hot-plugged with the same chardev and things will continue to work.
