iio: light: cm32181: return zero after writing calibscale

Browse Source 
The write_raw callback is documented to return 0 on success or a
negative error code.  However, the IIO_CHAN_INFO_CALIBSCALE case
returns 'val' (the user-supplied value) instead of 0.

Fix it by returning 0 on success, matching the behavior of other
calibscale implementations in the subsystem.
