[PATCH 1/2] iio:adc:ad7124: Parse configuration into correct local config structure.

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

The channel index is used before it's been read from the device tree
child node.  Move it down a few lines so it reflects the correct setting.

Noticed by inspection, so test appreciated.

Fixes: 7b8d045e497a ("iio: adc: ad7124: allow more than 8 channels")
