> OmKeyInfo#verifyAndGetKeyLocations calls
> OmKeyLocationInfoGroup#getLocationList() only to iterate over the block
> locations and populate allocatedBlockLocations.
> getLocationList() creates a flattened list on every call. This is unnecessary
> here because the grouped lists can be iterated directly.
> Use getLocationLists() with nested loops to avoid the intermediate list
> allocation. The behavior remains unchanged.
