i3c: Make remove callback return void
The driver core ignores the return value of struct bus_type::remove() because there is only little that can be done. To simplify the quest to make this function return void, let struct i3c_driver::remove() return void, too. This makes it obvious that returning an error code is a bad idea and future driver authors cannot get that wrong. Up to now there are no drivers with a remove callback, so there is no need to adapt drivers.
