#### Why I did it
The `PsuFan` in Mellanox platform queries for fan speed even though the relevant sysfs files do not exist. In `psud` the speed is already overwritten on presence, since the current implementation generates an error log, it is changed to query speed only on PSU presence and return 0 if there is no presence (Previously returned default value)
##### Work item tracking
- Microsoft ADO **(number only)**:
#### How I did it
Check presence using `get_presence` api and return fan speed only if it returns True
#### How to verify it
