wifi: nl80211: Update the documentation of NL80211_SCAN_FLAG_COLOCATED_6GHZ

Currently when NL80211_SCAN_FLAG_COLOCATED_6GHZ is set in the scan flags,
in addition to the co-located APs, PSC channels in the 6 GHz band would
also be scanned if the user space has asked for it. In other words, the
scan would happen on PSC channels & co-located 6 GHz channels that were
reported in the RNR IE.

Update the documentation of NL80211_SCAN_FLAG_COLOCATED_6GHZ flag to
reflect the above said behavior.
