mac80211: Add DS Parameter Set into Probe Request on 2.4 GHz
IEEE Std 802.11k-2008 added DS Parameter Set information element into Probe Request frames as an optional information on 2.4 GHz band (and mandatory, if radio measurements are enabled). This allows APs to filter out Probe Request frames that may be received from neighboring overlapping channels and by doing so, reduce the number of unnecessary frames in the air. Make mac80211 add this IE into Probe Request frames whenever the channel is known (i.e., whenever hwscan is not used).
