    net/iavf: fix VLAN strip setting after enabling filter

    For i40e kernel drivers which support either vlan(v1) or vlan(v2)
    VIRTCHNL OP, it will set strip on when setting filter on.
    But DPDK side will not change strip flag.
    To be consistent with DPDL side, explicitly disable strip again.
