iio: light: noa1305: Simplify noa1305_read_raw()

Browse Source 
The only channel this hardware supports is IIO_LIGHT, if the channel
is anything else, exit right away. The 'ret' variable is now always
only assigned by noa1305_measure(), do not initialize it anymore.
Update function parameter indent. No functional change.
