[PATCH net-next v11 4/8] net/mlx5: Add no-op implementation for setting tc-bw on rate objects

[Mark Bloch <mbloch@nvidia.com>]

From: Carolina Jubran <cjubran@nvidia.com>

Introduce `mlx5_esw_devlink_rate_node_tc_bw_set()` and
`mlx5_esw_devlink_rate_leaf_tc_bw_set()` with no-op logic.

Future patches will add support for setting traffic class bandwidth
on rate objects.
