Previously, we first assign alternative names to a network interface, then later change its main name if requested. So, we could not assign the name that currently assigned as the main name of an interface as an alternative name. So, we retry to assign the previous main name as an alternative name on later move uevent. However, that causes some confusing situation. E.g. if a .link file has ``` Name=foo AlternativeNames=foo baz ``` then even if the interface is renamed by a user e.g. by invoking 'ip link' command manually, the interface can be still referenced as 'foo', as the name is now assigned as an alternative name. This makes the order of name assignment inverse: the main name is first changed, and then the requested alternative names are assigned. And udevd do not assign alternative names on move uevent. Replaces #27506.
