net/mlx5: LAG, disable MPESW in lag_disable_change()
[ Upstream commit bd7b9f83fb9f85228c3ac9748d9cba9fab7fb5a2 ]
mlx5_lag_disable_change() unconditionally called mlx5_disable_lag() when
LAG was active, which is incorrect for MLX5_LAG_MODE_MPESW.
Hnece, call mlx5_disable_mpesw() when running in MPESW mode.
Fixes: a32327a3a02c ("net/mlx5: Lag, Control MultiPort E-Switch single FDB mode")
