[Mellanox] Fan speed should not be 100% when PSU is powered off (#9258)

Browse Source 
- Why I did it
When PSU is powered off, the PSU is still on the switch and the air flow is still the same. In this case, it is not necessary to set FAN speed to 100%.

- How I did it
When PSU is powered of, don't treat it as absent.

- How to verify it
Adjust existing unit test case
Add new case in sonic-mgmt
