iio temperature/mlx90632: silence a static checker warning
This shouldn't affect runtime at all, but Smatch complains that we
should check if mlx90632_read_ambient_raw() otherwise we
"ambient_new_raw" can be uninitialized.
drivers/iio/temperature/mlx90632.c:509 mlx90632_calc_ambient_dsp105()
error: uninitialized symbol 'ambient_new_raw'.
