igb: only use vlan_gro_receive if vlans are registered
This change makes it so that vlan_gro_receive is only used if vlans have been registered to the adapter structure. Previously we were just sending all vlan tagged frames in via this function but this results in a null pointer dereference when vlans are not registered.
