    LinuxKPI: 802.11: stop using hw_value on a channel
    
    During initial LinuxKPI 802.11 bringup looking at the usage in one
    driver I started using hw_value as an equivalent for ic_ieee.
    That is not correct.   Remove all usage but logging of hw_value
    from LinuxKPI 802.11 code and leave the field to the drivers.
    
    We have to go through some hoops to get the needed ic_ieee value
    but so be it.  At some point we may want to clear this up in
    net80211 (especially given we'll have to handle more per-band data
    in the future).
