usb-storage: ignore ZTE MF 823 card reader in mode 0x1225
This device automatically switches itself to another mode (0x1405) unless the specific access pattern of Windows is followed in its initial mode. That makes a dirty unmount of the internal storage devices inevitable if they are mounted. So the card reader of such a device should be ignored, lest an unclean removal become inevitable. This replaces an earlier patch that ignored all LUNs of this device. That patch was overly broad.
