Prevent data corruption for StorPool volumes

Prevents data corruption in cases where a VM is started on a new host while it is already running on another host

Scenario - if the host is down and the admin stops a VM with the
option `force=true` the admin will be able to start it on another host.
This may lead to a data corruption when the first host goes Up and the
volume is attached on both hosts.
