linux/thermal.h: rename KELVIN_TO_CELSIUS to DECI_KELVIN_TO_CELSIUS
The macros KELVIN_TO_CELSIUS and CELSIUS_TO_KELVIN actually convert between deciKelvins and Celsius, so rename them to reflect that. While at it, use a statement expression in DECI_KELVIN_TO_CELSIUS to prevent expanding the argument multiple times and get rid of a few casts.
