commit 5fb2c782f451a4fb9c19c076e2c442839faf0f76 upstream.

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.
