Fixes #49663

I tried to tread lightly with a small localized change because this needs to be picked to 1.7 and 1.6 as well.

I suspect this has been as issue since we started unmounting volumes on pod termination #37228

xref openshift/origin#14383

this is the same gating logic that we use for pod level cgroup creation and destruction, so it appears safe to me. will wait for bots to report green.

not for this pr, but a good future gating test would be to see if we get events about a pod from the node after its death. i am not sure how long it should wait, but maybe a node e2e could let us experiement on it in future.
