wifi: cfg80211: Handle specific BSSID in 6GHz scanning

When the scan parameters for a 6GHz scan specify a unicast
BSSID address, and the corresponding AP is found in the scan
list, add a corresponding entry in the collocated AP list,
so this AP would be directly probed even if it was not
advertised as a collocated AP.

This is needed for handling a scan request that is intended
for a ML probe flow, where user space can requests a scan
to retrieve information for other links in the AP MLD.
