nl/cfg80211: advertise OBSS scan requirement
wpa_supplicant will do OBSS scan for drivers that implement
auth/assoc API. Drivers that implement nl80211 connect API
(rather than auth/assoc) may need wpa_supplicant to do this
as well.
Add a new feature flag to inform it (wpa_s) that a driver
needs wpa_supplicant to do OBSS scans.
