WMI_CHAN_INFO_DFS flag should be set when configuring a DFS channel included in scan channel list. Without it, firmware will not send a probe request frame which is needed in connection to an AP configured with hidden SSID/network_id. So fix this to allow probe request frames to be sent in cases where a beacon frame has been seen on the channel first.
