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.
Fixes: 1a965d405fc6 ("drivers:iio:accel:mma8452: added cleanup provision in case of failure.")
