[RFC net-next 4/6] net: geneve: remove unused geneve_dev_create_fb

[Ilya Maximets <i.maximets@ovn.org>]

The only user was vport-geneve in openvswitch and now it is gone.

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.
