net/mlx5e: Update netdev features after changing XDP state

Some features (LRO, HW GRO) conflict with XDP. If there is an attempt to enable such features while XDP is active, they will be set to `off [requested on]`. In order to activate these features after XDP is turned off, the driver needs to call netdev_update_features(). This commit adds this missing call after XDP state changes.
