With the device plugin node reboot test fixed, we can see in testgrid
[node-kubelet-containerd-flaky](https://testgrid.k8s.io/sig-node-containerd#node-kubelet-containerd-flaky)
that the test is passing consitently and we can remove the flaky label.
With the test not flaky anymore, we can validate new PRs against it
and ensure we don't cause regressions.
