[net 8/9] net/mlx5: E-Switch, Fail mlx5_esw_modify_vport_rate if qos disabled

[Saeed Mahameed]

From: Eli Cohen <e...@nvidia.com>

Avoid calling mlx5_esw_modify_vport_rate() if qos is not enabled and
avoid unnecessary syndrome messages from firmware.

Fixes: fcb64c0f5640 ("net/mlx5: E-Switch, add ingress rate support")
