since igbvf_vlan_offload_config is dummy function, we no need to call
it here.

I think we can simplify it to just implement the missed VLAN offload
ops, it will make the VLAN filter by ID to work.
BTW, the API 'rte_eth_dev_set_vlan_offload' will check the mask vs
capabilities, so we can just always "return 0", that means a dummy
function for VF.
static int
eth_igbvf_vlan_offload_set(__rte_unused struct rte_eth_dev *dev,
__rte_unused int mask)
{
return 0;
}
