net/mlx5e: SHAMPO: Improve hw gro capability checking

Browse Source 
Add missing HW capabilities, declare the feature in
netdev->vlan_features, similar to other features in mlx5e_build_nic_netdev.
No functional change here as all by default disabled features are
explicitly disabled at the bottom of the function.
