    net/iavf: fix single VLAN strip in double VLAN mode
    
    In Double VLAN Mode (DVM) i.e. when RTE_ETH_RX_OFFLOAD_VLAN_EXTEND
    is enabled iavf_config_vlan_strip_v2() only toggles the inner
    VLAN strip setting (0x8100) for the RTE_ETH_RX_OFFLOAD_VLAN_STRIP
    offload, while the outer VLAN strip is controlled independently
    through the QinQ strip path.
    
    However, in DVM, most hardwares place a single (non-QinQ) VLAN
    tag in the outer position
    As a result, when a single VLAN packet is received and the
    application disables single VLAN tag stripping, only the inner
    VLAN tag strip gets turned off and the outer VLAN tag strip
    stays enabled.
    Hence, the single VLAN tag still gets stripped.
    This does not honor the application's request.
    
    This patch fixes the aforesaid case.
    When DVM and QinQ stripping are both enabled, also apply the strip
    enable/disable to the outer VLAN so that single VLAN packets received
    in double VLAN mode respect the single VLAN strip configuration.
