wifi: cfg80211: honor WIPHY_FLAG_SPLIT_SCAN_6GHZ in cfg80211_conn_scan

If a user uses iw to connect to a network and we don't have any
information about the existing networks, cfg80211 will trigger a scan
internally even if the user didn't ask for a scan. This scan is
implemented by cfg80211_conn_scan(). This function called rdev_scan()
directly without honoring the WIPHY_FLAG_SPLIT_SCAN_6GHZ flag.
Use cfg80211_scan instead, this will split the scan if the low level
driver asked to.
