libertas_tf: fix signal reporting
Instead of exposing the signal-to-noise ration, calculate the actual signal
level taking the noise floor into account.
Also, flip the SIGNAL_DBM bit on, so that mac80211 exposes the signal
level along with the station info in scan results. This fills
NetworkManager's "nmcli d wifi output" output with colors, bars and joy.
