Description of problem:
VMSnapshot breaks after OCP Upgrade 4.10.z -> 4.11.z

Version-Release number of selected component (if applicable):
We saw this:
OCP Upgrade 4.10.47 -> 4.11.22, CNV v4.10.8-8
OCP Upgrade 4.10.45 -> 4.11.20, CNV v4.10.8-2
OCP Upgrade 4.10.44 -> 4.11.18, CNV v4.10.7-24

How reproducible:
Only on OCP upgrade, not on CNV upgrade

Steps to Reproduce:
1. Create a VMSnapshot before the upgrade
2. Upgrade OCP
3. Try to create a VMRestore from the VMSnapshot that was created before the upgrade

Actual results:
"status":"Failure","message":"admission webhook \\"virtualmachinerestore-validator.snapshot.kubevirt.io\\" denied the request: VirtualMachineSnapshot \\"snapshot-vm-snapshot-upgrade-b-1673173618-7427866\\" is not ready to use","reason":"Invalid","details":{"causes":[{"reason":"FieldValueInvalid","message":"VirtualMachineSnapshot \\"snapshot-vm-snapshot-upgrade-b-1673173618-7427866\\" is not ready to use","field":"spec.virtualMachineSnapshotName"}]},"code":422}\n'
