[rdma-next 07/22] RDMA/core: Remove unimplemented node_types and node transport

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Leon Romanovsky <leonro-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

There is no need to carry code, which is not implemented in any
underlying hardware. This patch removes unimplemented node_types and
their respective node transport layers.

Signed-off-by: Leon Romanovsky <leonro-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>
