rh: revise correction data usage

- UHD's calibration utilities use the LO frequency, so this is the
  frequency we should be using too.
- Disables loaded corrections in lowband, as the utilities will not
  generate valid corrections at these frequencies. Manual corrections
  can still be added via the property tree.
- Changed corrections logging to include frequency and less certainty
  of the correction file's existence.
