The point from Nicolas here was that the workqueue is allocated in
i3c_master_init so you should have a function to destroy it instead of
having to do that separately in i3c_primary_master_register. The same is
true for the put_device. Or you have to ensure i3c_masterdev_release
is called when i3c_primary_master_register fails.
