Fix kvm remove when domain is not running

[josedonizetti]

Fix for #4319

This PR is considering only the case when the running domain was deleted, with virsh destroy DOMAIN_NAME, and not the problem of undefining a domain, I'll create a separate PR for that to simplify review.

Hi @josedonizetti. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Looks great. Just two tiny nitpicks. Thank you for making the kvm2 driver more robust!
