    LinuxKPI: 802.11: deal with wdev list, and misc
    
    Fill in more (lvif) wdev details and add it to the list under the wiphy
    struct so that iterators at least work and find the (one) device.
    This is needed for the upcoming espwl(4) driver.
    
    misc: add WPI-SMS4 to the list of cipher suits (we won't support it but
    at least print the name).
    
    MFC after:      3 days
