Ivan Zaentsev 1ad8f7fc4a w1: w1_therm: Fix conversion result for negative temperatures ...

commit 2f6055c26f upstream.

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: 9ace0b4dab (w1: w1_therm: Add support for GXCAS GX20MH01 device.)
