dpdk: Disable VLAN filtering for VLAN sub-interface in i40e driver

When creating a VLAN sub-interface on a Fortville i40e DPDK VF,
the data plane does not work properly.

Enabling vlan filter offload overrides the VLAN strip offload setting to on.
The VLAN strip offload must be disabled for VPP VLAN sub-interfaces to work.
