Fix -Wswitch warning

[Tilka]

Fixes enumeration value ‘LANGUAGE_UNKNOWN’ not handled in switch

[lioncash]

This will still cause warnings on higher warning levels (using default in a switch with enum types (ie. strictly defined case values)). The correct way of doing this is:

u8 WiiConfigPane::GetSADRCountryCode(DiscIO::IVolume::ELanguage language)
{
    switch (language)
    {
    case DiscIO::IVolume::LANGUAGE_JAPANESE:
        return 1;   // Japan
    case DiscIO::IVolume::LANGUAGE_ENGLISH:
        return 49;  // USA
    case DiscIO::IVolume::LANGUAGE_GERMAN:
        return 78;  // Germany
    case DiscIO::IVolume::LANGUAGE_FRENCH:
        return 77;  // France
    case DiscIO::IVolume::LANGUAGE_SPANISH:
        return 105; // Spain
    case DiscIO::IVolume::LANGUAGE_ITALIAN:
        return 83;  // Italy
    case DiscIO::IVolume::LANGUAGE_DUTCH:
        return 94;  // Netherlands
    case DiscIO::IVolume::LANGUAGE_SIMPLIFIED_CHINESE:
    case DiscIO::IVolume::LANGUAGE_TRADITIONAL_CHINESE:
        return 157; // China
    case DiscIO::IVolume::LANGUAGE_KOREAN:
        return 136; // Korea
    case DiscIO::IVolume::LANGUAGE_UNKNOWN:
        break;
    }

    PanicAlert("Invalid language");
    return 1;
}
