Fix of create a template from a StorPool snapshot on another zone (#11490)

Browse Source 
* Fix of create template from snapshot on another zone

When a snapshot has a copy on StorPool primary storage in another zone, but the original snapshot resides on secondary storage, creating a template from the copied snapshot results in the template being created in the first zone.
If the snapshot.backup.to.secondary setting is disabled, and a user creates a volume or template from a snapshot, the snapshot is temporarily backed up to secondary storage during the operation. After the operation, this backup should be deleted. However, the snapshot currently remains on both primary and secondary storage.

* update snapshot info depending on the data store role
