Handle OCC EAGAIN & EREMOTEIO in 4.13

This is a temporary fix until the following issues are completed:
    openbmc/openbmc#2327
    openbmc/openbmc#2329

When an EAGAIN or an EREMOTEIO return code is received by hwmon
from the OCC driver in the 4.13 kernel, they should be translated to
an unavailable sensor(0x00) and failed sensor(0xFF) scaled values
respectively. This will keep the OCC hwmon instance running and allow
applications to continue using these sensors as they were reported under
the mainline openbmc/linux 4.10 kernel.

Tested:
    Verified return codes are caught and sensor value modified
