====================
Drop NETDEV_UNREGISTER_FINAL (was unnamed)

This series drops unused NETDEV_UNREGISTER_FINAL
after some preparations.

v2: New patch [2/3]. Use switch() in [1/3].

The first version was acked by Jason Gunthorpe,
and [1/3] was acked by David Ahern.

Since there are differences to v1, I haven't added
Acked-by tags of people. It would be nice, if you
fill OK to tag v2 too.
