qcacmn: Modularize finding radar affected sub channel function

Browse source 
The radar affected sub channel are determined by the bangradar type,
whether sub-channel marking is enabled or not, the center frequency
of the band on which the radar was detected. This block of code is present
in processing radar indication function and can be modularized.

Move the logic to find radar affected sub-channels into a single function.
