iio: adc: ti-ads131e08: return correct error code

The error code returned from devm_iio_trigger_register() inturn
iio_trigger_register() can be other than -ENOMEM. Hence return the
same value as it was returned from the function call.
This change makes devm_iio_trigger_register() handling uniform with
other iio drivers.
