> temp_auto_temp_off_store() subtracts an unrestricted long from the zone
> limit before clamping the resulting hysteresis. Extreme inputs can
> overflow this subtraction and select the wrong end of the hysteresis

> Bound the requested stop temperature before calculating the difference.
> A signed 8-bit zone limit and a maximum hysteresis of 15 degrees require
> only the -143..127 degree range.
