What you expected to happen:
Cleanup should be resilient to the CRDs not being present.

How to reproduce it:
As above.

Anything else we need to know?:
Discovered when using HCO to delete both KubeVirt and SSP at the same time.

Environment:

• KubeVirt version (use virtctl version):
• Kubernetes version (use kubectl version):
• SSP Operator version:
• VM or VMI specifications:
• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release):
• Kernel (e.g. uname -a):
• Install tools:
• Others:
