[PATCH rdma-rc 04/12] IB/mlx5: Fix memory leak in query device

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

From: Majd Dibbiny <majd-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

We need to free dev->port when we fail to enable RoCE or
initialize node data.

Fixes: 0837e86a7a34 ('IB/mlx5: Add per port counters')
