Make IpmbSensor properly clear sensor value on PowerOff

Previously when platform was put in Off state, IpmbSensor stopped
polling ON-only sensors, which is fine.
However, it didn't clear sensor value and availability state (which is normally done
by updateValue() for such cases.

This commit introduces following changes:
- updateValue() in invalid power state sets sensor to 'nan'
- modified IpmbSensor to use the same logic as updateValue()
  in optimized (skip reading in invalid state) flow

Testing:
- put platform in shutdown state - sensor Value is set to 'nan',
  Available is 'false', Functional still 'true'
- after restarting platform - values and flags goes back to normal
