The kube-apiserver pod ran into CrashLoopBackOff due to the PodNetworkConnectivityCheck fail when the cluster upgrade from 4.6.0-rc.4 to 4.7 nightly build

Version-Release number of selected component (if applicable):
4.6.0-rc.4

How reproducible:


Steps to Reproduce:
1.install a cluster with version 4.6.0-rc.4
2.upgrade the cluster to 4.7.0-0.nightly-2020-10-17-034503

Actual results:
2.upgrade fail, co openshift-apiserver degrade, and namespace pods ran into CrashLoopBackOff status due to ConnectivityCheck fail


Expected results:
2.upgrade succeed
