ath11k: Identify DFS channel when sending scan channel list command

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.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1
