Subject: net/mlx5: E-Switch, Fail mlx5_esw_modify_vport_rate if qos disabled
Patch-mainline: v5.10-rc5
Git-commit: 5b8631c7b21ca8bc039f0bc030048973b039e0d2
References: jsc#SLE-8464
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")
