Log message:
On 5GHz channels, keep the most recent RSSI measurement from a probe
response in case a lower RSSI is measured for a subsequent beacon.

I have run into a 5Ghz AP which sends beacons with very low Tx power for some
reason, while probe responses are transmitted with reasonable signal strength.
This change ensures such 5GHz APs will be considered as a reasonable choice
during access point selection.

Discussed with sthen@, Patrick Dohman, and others on tech@
