这里如果有多个chassis 或者 只有一个chassis 但是和 node name不一致，直接触发 gc。

节点被删除时，chassis 会被删除，但 ovn-controller 还会自动注册一个 chassis，这个 chassis 没有 external-ids:vendor=kube-ovn。后续如果一个同名且同 IP 的节点加入集群，ovn-controller 无法注册新的 chassis。

那就是说两种情况：
- 你说的这种，node之前被清理了，但是 ovn-controller 还在跑或者重新跑，导致有脏记录。 这种node不存在，但是有多余的chassis，现在你的 gcChassis 已经覆盖到了。 但是 node 更新的时候触发gc的逻辑还是有问题，目前没触发到。
- 我清理了整个集群，想快速重建下kube-ovn，可能会出现有两个chassis的情况
