failure to get OCC temp 0

Failure to get OCC temp 0 as a (temperature is no longer available)
instead code gets a file read error with errno = 11 (Resource
temporarily unavailable). This will indicate temp is no longer
available 0 for Fan Control.
Tested: HW error inject on DIMM to cause OCC to send a temp 0 to BMC.
