drivers:iio:accel:mma8452: added cleanup provision in case of failure.
mma8452_set_freefall_mode can return -ve value in case if
i2c_smbus_read_byte_data fails. This function is called from mma8452_probe,
and returning -ve value from probe indicates probe failure. Need to call
iio_triggered_buffer_cleanup & iio_trigger_cleanup in this case.
