cfg80211: don't add non transmitted BSS to 6GHz scanned channels
When adding 6GHz channels to scan request based on reported
co-located APs, don't add channels that have only APs with
"non-transmitted" BSSes if they only match the wildcard SSID since
they will be found by probing the "transmitted" BSS.
