Subject: [PATCH iproute2-rc v1 2/2] rdma: Properly print device and link names in CLI output

From: Leon Romanovsky <leonro@...dia.com>

The citied commit broke the CLI output and printed ifindex/ifname
instead of dev/link.

Before:
[leonro@vm ~]$ rdma res show qp
link mlx5_0/lqpn 1 type GSI state RTS sq-psn 0 comm ib_core
[leonro@vm ~]$ rdma res show cq
ifindex 0 ifname rocep0s9 cqn 0 cqe 1023 users 2 poll-ctx WORKQUEUE adaptive-moderation on comm ib_core

After:
[leonro@vm ~]$ rdma res show qp
link mlx5_0/- lqpn 1 type GSI state RTS sq-psn 0 comm [ib_core]
[leonro@vm ~]$ rdma res show cq
dev rocep0s9 cqn 0 cqe 1023 users 2 poll-ctx WORKQUEUE adaptive-moderation on comm [ib_core]

It was missed because rdmatool mostly used in JSON mode.

Fixes: b0a688a542cd ("rdma: Rewrite custom JSON and prints logic to use common API")
