Legacy VLAN implementation allows for untrusted VF to have 8 VLAN filters, not counting VLAN 0 filters. Current VLAN_V2 implementation lowers available filters for VF, by counting in VLAN 0 filter for both TPIDs. Fix this by counting only non zero VLAN filters. Without this patch, untrusted VF would not be able to access 8 VLAN filters.
