[Mellanox] Add N/A as a valid fan direction for Nvidia platforms (#17930)

Browse Source 
- Why I did it
On some Nvidia platforms, fan direction could not be determined. Therefore 'N/A' becomes a valid value for those cases.

- How I did it
Add 'N/A' to the valid fan direction mapping, to avoid an error in the log.

- How to verify it
Check fan direction on Nvidia platforms, and make sure there aren't errors in the log.
