mac80211: conditionally advertise HE in probe requests
While building probe requests, only enable HE capability if there are actually any channels in the band with HE enabled, otherwise we're not really capable. We're doing the same in association requests, so doing it here makes it consistent. This also makes HE not appear available if it isn't due to regulatory constraints.
