hwmon: (drivetemp) Return -ENODATA for invalid temperatures

Holger Hoffstätte observed that Samsung 850 Pro may return invalid
temperatures for a short period of time after resume. Return -ENODATA
to userspace if this is observed.

Fixes:  5b46903d8bf3 ("hwmon: Driver for disk and solid state drives with temperature sensors")
