w1: w1_therm: Fix conversion result for negative temperatures
DS18B20 device driver returns an incorrect value for negative temperatures
due to a missing sign-extension in w1_DS18B20_convert_temp().
Fix by using s16 temperature value when converting to int.
Fixes: 9ace0b4dab1c (w1: w1_therm: Add support for GXCAS GX20MH01 device.)
