wifi: cfg80211: update the time stamps in hidden ssid

Browse Source 
In hidden SSID we have separate BSS entries for the beacon and for the
probe response(s).
The BSS entry time stamps represent the age of the BSS;
when was the last time we heard the BSS.
When we receive a beacon of a hidden SSID it means that we heard that
BSS, so it makes sense to indicate that in the probe response entries.
Do that.
