iio: light: cm32181: Clean up the probe function a bit
3 small cleanups to cm32181_probe():
1. Do not log an error when we fail to allocate memory (as a general
rule drivers do not log errors for this as the kernel will already
have complained loudly that it could not alloc the mem).
2. Remove the i2c_set_clientdata() call, we never use i2c_get_clientdata()
or dev_get_drvdata() anywhere.
3. Add a dev helper variable and use it in various places instead of
&client->dev.
