qcacld-3.0: Remove radar event if dfs_channel_switch is disable

Browse source 
Currently, DUT is able to detect the radar event
causing channel switch even if disable dfs channel
switch ini is set. Due to this, there is a chance
of unwanted CSA.

Adding check for disable dfs channel switch ini before
detecting the radar. If gDisableDFSChSwitch = 0 then
detect the radar event else ignore the radar event.
