hwmon: (f71882fg) Fix negative temperature
All temperature of Fintek superio hwmonitor that using 1-byte reg will use
2's complement.
In show_temp()
temp = data->temp[nr] * 1000;
When data->temp[nr] read as 255, it indicate -1C, but this code will report
255C to userspace. It'll be ok when change to:
temp = ((s8)data->temp[nr]) * 1000;
