w1: w1 temp: fix negative termperature calculation
Fix regression caused by commit 507e2fbaaacb6f164b4125b87c5002f95143174b
("w1: w1 temp calculation overflow fix") whereby negative temperatures for
the DS18B20 are not converted properly.
When the temperature exceeds 32767 milli-degrees the temperature overflows
to -32768 millidegrees. These are both well within the -55 - +125 degree
range for the sensor.
