qcacmn: Remove radar parameter translation for partial-offload chips

The routine 'dfs_translate_radar_params()' translates the radar found
offsets given by a 160MHz detector which ranges from -80MHz to +80MHz
to that of the offsets given by an 80MHz detector that ranges from
-40MHz to +40Mhz. The same function also translates the segment ID from a
single-detector(160MHz) model to a two-detector model(80Mhz). This routine
is unnecessarily called for partial-offload chipsets which do not support
True 160MHz.

Do not call the function 'dfs_translate_radar_params()' from
'dfs_process_radar_ind()' which is common for both partial-offload and
full-offload. Call it from the full-offload specific radar action
function 'tgt_dfs_process_radar_ind()'.
