wlan: LFR Enhancements To Channel Caching Algorithm.

LFR maintain an occupied channel list (aka channel cache) to keep track
of which channels to scan. Channel cache does not get updated if
neither the framework nor the driver issues a scan (i.e. outside of
LFR). Due to this, the channel cache only has channels obtained as part
of the scan during initial association at some location.
