iio: adc: ad4000: Check for error code from devm_mutex_init() call
[ Upstream commit 8ebfd09255219ae55f8a101f6aeb0f64dd780d88 ]
Even if it's not critical, the avoidance of checking the error code
from devm_mutex_init() call today diminishes the point of using devm
variant of it. Tomorrow it may even leak something. Add the missed
check.
