Subject: [PATCH 2/3] iio: dac: ad5592r: un-indent code-block for scale read

The next rework may require an unindentation of a code block in
ad5592r_read_raw(), which would make review a bit more difficult.

This change unindents the code block for reading the scale of the
non-temperature channels.
