iio: humidity: hdc100x: fix IIO_HUMIDITYRELATIVE channel reporting

BugLink: https://bugs.launchpad.net/bugs/1858424
commit 342a6928bd5017edbdae376042d8ad6af3d3b943 upstream.

The IIO_HUMIDITYRELATIVE channel was being incorrectly reported back
as percent when it should have been milli percent. This is via an
incorrect scale value being returned to userspace.
