at present, eventhough the checkReservation works for both volume
and snapshot, the arg parentName make sense only for snapshot cases
renaming that arg to more approprite

@ -264,7 +264,7 @@ CheckReservation checks if given request name contains a valid reservation
- If there is a valid reservation, then the corresponding ImageData for the volume/snapshot is returned
- If there is a reservation that is stale (or not fully cleaned up), it is garbage collected using
the UndoReservation call, as appropriate
- If a snapshot is being checked, then its source is matched to the parentName that is provided
- If a snapshot is being checked, then its source is matched to the snapParentName that is provided
NOTE: As the function manipulates omaps, it should be called with a lock against the request name
held, to prevent parallel operations from modifying the state of the omaps for this request name.
