[PATCH v2 10/18] iio: amplifiers: hmc425a: 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 at kernel.org>

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