fix Skoda MQTT: stop reconnect loop on 'Not authorized' server error

Known Skoda server-side issue (skodaconnect/myskoda#554,
homeassistant-myskoda#1062). On 'Not authorized', stop the client
immediately instead of reconnecting endlessly or triggering token
refresh loops. Next scheduled token refresh (every 54min) will
retry connectMqtt() with fresh credentials.
