device: don't flush addresses when unmanaging assumed devices

When a assumed software device is brought down externally, it becomes
UNMANAGED_EXTERNAL_DOWN and its state goes from ACTIVATED directly to
UNMANAGED. In such case, we shouldn't flush the IP configuration
(addresses and routes) present on the device.

To fix this, clean up the device with CLEANUP_TYPE_KEEP and modify
nm_device_cleanup() not to flush addresses and devices with such flag.
