[PATCH rdma-next 3/6] RDMA/{cma, ucma}: Simplify and rename rdma_set_ib_paths

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

From: Parav Pandit <parav-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

Since 2006 there has been no user of rdmacm based application to make use
of setting multiple path records using rdma_set_ib_paths API.

Therefore code is simplified to allow setting one path record entry.
Now that it sets only single path, it is renamed to reflect the same.
