occ-sensors: Check if OCC is reset while reading inband sensors
OCC may not be able to mark the sensor buffer as invalid while going
down RESET. If OCC never comes back we will continue to read the stale
sensor data. So verify if OCC is reset while reading the sensor values
and propagate the appropriate error.
