ice: Fix max VLANs available for VF
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.
