platform/x86: asus-wmi: Fix support for showing middle fan RPM 

After the addition of the mid fan custom curve functionality various
incorrect behaviour was uncovered. This commit fixes these areas.

- Ensure mid fan attributes actually use the correct fan ID
- Correction to a bit mask for selecting the correct fan data
- Refactor the curve show/store functions to be cleaner and
  match each others layout
