wifi: cfg80211: update the time stamps in hidden ssid
[ Upstream commit 185cc2352cb1ef2178fe4e9a220a73c94007b8bb ]
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.
