[PATCH 08/12] iio: light: rohm-bu27034: Fix error return

[Matti Vaittinen]

From: Matti Vaittinen <mazziesaccount@xxxxxxxxx>

When BU27034 fails to read gain value at integration-time setting, it
returns 0. This leaves caller unaware of the fact that setting the
integration time failed.

Fix this by returning the relevant error instead of zero.
