iio:light:us5182d: Improve error reporting for problems during .remove()
Returning an error value in an i2c remove callback results in a generic
error message being emitted by the i2c core, but otherwise it doesn't
make a difference. The device goes away anyhow and the devm cleanups are
called.
So instead of triggering the generic i2c error message, emit a more
helpful message if a problem occurs and return 0 to suppress the generic
message.
This patch is a preparation for making i2c remove callbacks return void.
