    netlink: use ifmedia to provide vlan interface operstate.
    
    Netlink customers rely on admin and operational state when
     working with interfaces. The current implementation retuns
     "unknown" operstate for all interface types except IFT_ETHER
     and IFT_LOOP.
    
    This change updates the code to fetch vlan operstate in the same way
     as for the ether interfaces. For the rest of the interface types,
     operstate is now mapped to the admin state.
