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.
[ This fixes bugzilla entry 15582 -Eric Dumazet]
