[PATCH] Add non-PSC channels to 6GHz scan request

When non_coloc_6ghz = false, the STA is expected to scan for
colocated APs. However, if the colocated AP is on a non-PSC
channel, it will not be detected during the 6GHz-only scan
because the frequency list is limited to PSC channels. Even when
the NL80211_SCAN_FLAG_COLOCATED_6GHZ is set, the cfg80211 only
scans a subset of the channels in the original 6GHz scan request.
Therefore, this patch adds non-PSC channels to the original 6GHz
scan request.
