Check fan speed before check fan status (#6586)

**- Why I did it**
In thermalctd, when speed of fan exceeds threshold, the fan status will be saved as "bad". So in system health, it is better to check fan speed before fan status. In this case, if fan speed exceeds threshold, we get more detailed information.

**- How I did it**
Move fan speed check logic before fan status check

**- How to verify it**
Manual test
