[Mellanox] Add more unit test coverage for platform API (#15842)
- Why I did it
Increase UT coverage for Nvidia platform API code

Work item tracking
Microsoft ADO (number only):

- How I did it
Focus on low coverage file:
1. component.py
2. watchdog.py
3. pcie.py

- How to verify it
Run the unit test, the coverage has been changed from 70% to 90%
