If you add a PDB for it, that should help:

apiVersion: policy/v1
kind: PodDisruptionBudget
metadata:
  name: kube-dns-autoscaler-pdb
  namespace: kube-system
  labels:
    app: kube-dns-autoscaler
spec:
  maxUnavailable: 1
  selector:
    matchLabels:
      k8s-app: kube-dns-autoscaler

(You might do the same thing for kube-dns for the same reason.)
