Handle OCC active sensor updates prior to host runtime

On some systems, occ-control was getting notified that the OCCs were
active before the host reached runtime state. This would prevent
occ-control from starting communication with the OCCs.

The fix will ignore the early OCC Active sensor enabled messages and
once the host gets to runtime, it will re-query the sensors to ensure
they are still active.

Verified on fresh boot, warm boot, BMC reset, warm boot after BMC reset
on a system that exhibited the early sensors and one that did not.

Also removes an unnecessary InternalFailure when a sensor was cleared,
but no OCC objets were found.
