Cheat System: Fix a couple bugs with CheatDBFile::LoadGameList() when reading the entire database's game list. 

- Fix a bug where loading all database game entries from an encrypted database would result in reading gobbledygook.
- Fix a bug where calling CheatDBFile::LoadGameList() for all database game entries would always return 0 entries rather than the actual number of found entries.
