Description of problem:
When VM creation fails during the cloning procedure, deletion of the VM would delete the DataVolume, but the cdi-tmp-* PVC that was created during the procedure remains.

Version-Release number of selected component (if applicable):
OpenShift 4.10.16
OpenShift Virtualization 4.10.1

How reproducible:
Always

Steps to Reproduce:
1. The source disk is in a PVC in the openshift-virtualization-os-images namespace and uses a Ceph storage class.
2. The creation of the VM in a different namespace fails during the cloning procedure.
3. After the failure, the DataVolume is deleted.

Actual results:
In the source namespace openshift-virtualization-os-images there's a leftover cdi-tmp-* PVC that it's stuck in "Pending" state.

Expected results:
The cdi-tmp-* PVC is removed too.

Additional info:
This looks like the same issue reported in these links, which in theory was fixed in 4.8.1:
