Subject: iio: mma8452: Add missed iio_device_unregister() call in
mma8452_probe()

The function iio_device_register() was called in mma8452_probe(). But the function iio_device_unregister() was not called after a call of the function mma8452_set_freefall_mode() failed. Thus add the missed function call for one error case.
