stmmac_vlan_restore() unconditionally calls stmmac_vlan_update() when
NETIF_F_VLAN_FEATURES is set. On platforms where priv->hw->vlan (or
->update_vlan_hash) is not provided, stmmac_update_vlan_hash() returns
-EINVAL via stmmac_do_void_callback(), resulting in a spurious
"Failed to restore VLANs" error even when no VLAN filtering is in use.
Remove not needed comment.
Remove not used return value from stmmac_vlan_restore().
Tested on Orange Pi Zero 3.
