mac80211: remove HW_SIGNAL_DB
Giving the signal in dB isn't much more useful to userspace than giving the signal in unspecified units. This removes some radiotap information for zd1211 (the only driver using this flag), but it helps a lot for getting cfg80211-based scanning which won't support dB, and zd1211 being dB is a little fishy anyway.
