Subject: [PATCH] iio: light: cm3605: Fix an error handling path in cm3605_probe()

The commit in Fixes also introduced a new error handling path which should
goto the existing error handling path.
Otherwise some resources leak.

Fixes: 0d31d91e6145 ("iio: light: cm3605: Make use of the helper function dev_err_probe()")
