qcacmn: Reorder function calls when radar found during precac

  During Zerowait DFS, when radar is hit, the NOL IE element that
  is being sent to its uplink is prepared after the precac timer
  is turned off, which returns wrong center frequency
  information for secondary segment.
  This center frequency is used to built the list of subchannels to
  be sent to root, which in turn are all 0s.

  Reorder the function calls to prepare the IE before the
  precac timer is turned off when radar is found so that the
  list of subchannels are built properly.
