ath11k: fix radar detection in 160 Mhz

Browse Source 
Radar detection fails in the secondary 80 MHz when the
the AP's primary 80 MHz is in non-DFS region in 160 MHz.

This is due to WMI channel flag WMI_CHAN_INFO_DFS_FREQ2 is not set
properly in case of the primary 80 MHz is in non-DFS region.
HALPHY detects the radar pulses in the secondary 80 MHz only when
WMI_CHAN_INFO_DFS_FREQ2 is set.

Fix this issue by setting WMI channel flag WMI_CHAN_INFO_DFS_FREQ2
based on the radar_enabled flag from the channel context.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.5.0.1-01100-QCAHKSWPL_SILICONZ-1
