device: retry creation of default connection after link is initialized

Browse source 
When a new link is detected, NM tries to generate a default "Wired
connection" in nm_settings_device_added(), but if the link has not
been initialized by udev yet the function returns early because
priv->unmanaged_flags = UNMANAGED_PLATFORM_INIT.

To be sure that a default connection is created is such situation, we
need to call again nm_settings_device_added() after link
initialization.
