[PATCH net V2] net/mlx5: Lag, reset vport speed on MPESW teardown

[Tariq Toukan]

From: Or Har-Toov <ohartoov@xxxxxxxxxx>

mlx5_lag_disable_mpesw() never called mlx5_lag_reset_vports_speed(),
unlike regular LAG teardown in mlx5_do_bond(), leaving stale cached and
FW-configured speeds after MPESW is torn down.

Call it from mlx5_lag_disable_mpesw() as well, so the reset is paired
with mlx5_lag_set_vports_agg_speed() on the MPESW path too.

Fixes: 50f1d188c580 ("net/mlx5: Propagate LAG effective max_tx_speed to vports")
