serial: sccnxp: Improve error message if regulator_disable() fails

Returning an error code from .remove() makes the driver core emit the
little helpful error message:

	remove callback returned a non-zero value. This will be ignored.

and then remove the device anyhow.

So replace the error return (and with it the little helpful error
message) by a more useful error message.
