Fix dry run using stop virctl command with grace-period

[fossedihelm]

What this PR does / why we need it:
Fix a bug that occurs when a user uses both --dry-run and --grace-period=<value> in stop virctl command. It causes the patch of the vmi with the given grace-period which should not happen according to the dry-run specification. This happens due to a missed propagation of the DryRun value in the patch of the VMI, which occurs only when also grace-period is given

Hi @fossedihelm. Thanks for your PR.

I'm waiting for a kubevirt 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 good, only one nit found, but no need to tackle this here.
