ovirt_vm: Fix initialization of cloud init (#47348)

Fixes: https://github.com/ansible/ansible/issues/45900

This PR fixes the case when the cloud_init_persist was used, but we
still sent use_cloud_init=False, which is in oVirt API evaluated as not
to use cloud_init in first VM execution. This patch is changing it to
send just None, instead of False.
