iio: humidity: hdc100x: fix IIO_TEMP channel reporting

BugLink: http://bugs.launchpad.net/bugs/1607404
commit 09bc0ddaab6cab0fa95a67d5535ec772e2671193 upstream.

IIO_TEMP channel was being incorrectly reported back as Celsius when it
should have been milliCelsius. This is via an incorrect scale value being
returned to userspace.
