[PATCH] wifi: mac80211: Update bssid indicator with real BSS numbers

[Allen Ye]

From: "Allen.Ye" <allen.ye@mediatek.com>

The cnt member in mbssid is the count of total number of MBSSID elements
instead of BSSID. Therefore, we fix this by reading the MaxBSSID Indicator
field directly.

All the names, both in From and s-o-b, use '.' instead of space in names.
