When starting a background scan, free the nodes table to ensure we
get an up-to-date view of APs around us. In particular, we need to
kick out the AP we are associated to. Otherwise, our current AP might
stay cached if it is turned off while we are scanning, and we could
end up picking a now non-existent but "good looking" AP over and over.
