Ian Dall 9a6a1ecd9e w1: w1 temp: fix negative termperature calculation
Fix regression caused by commit 507e2fbaaa
("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.
