qcacmn: Increment num_radar_detects for FO everytime radar is detected

With the current implementation, dfs->wlan_dfs_stats.num_radar_detects
is incremented for radar detections in partial offload alone. For FO,
this stat was not incremented. As a result, when the number of times
radar has been detected is queried with radartool, the stat always
returns 0.

Fix this by incrementing this stat for FO chipsets as well.
