[RFC net-next 6/6] net: vxlan: remove unused vxlan_dev_create

[Ilya Maximets]

The vport-vxlan in openvswitch was the last user and it is now gone.

And we can now rename the internal function to have a better name.

Note: since it's an exported symbol, there is a possibility that some
out-of-tree module is using it.  So, alternative is to deprecate it
instead by adding a warning if it is ever called.
