    LinuxKPI: 802.11: fix lkpi_scan_ies_add() channel lookup
    
    When looking up the channel we may not get a result if no flags are
    passed in as net80211 channel list setup and lookup coding requires a
    matching flag (band).  So pass in IEEE80211_CHAN_[AG] depending on band
    to increase the chances of finding a base channel and from that derive
    rates, etc.
