[PATCH v2 05/18] iio: adc: ltc2497: Simplify with dev_err_probe()

Common pattern of handling deferred probe can be simplified with
dev_err_probe(). Less code and also it prints the error value.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

Changes since v1:
1. Wrap dev_err_probe() lines at 100 character
