Staging: iio: Simplify return logic 

Author: Cristina Opriceana <cristina.opriceana@gmail.com>

This patch removes the conditional return of the ade77*_probe functions
based on the return values of iio_device_register as the latter
returns 0 or ret, the same as the checked values.

Warning found by coccinelle.
