The user can open multiple device FDs if it likes, however these open() functions call vfio_register_notifier() on some device global state. Calling vfio_register_notifier() twice in will trigger a WARN_ON from notifier_chain_register() and the first close will wrongly delete the notifier and more. Since these really want the new open/close_device() semantics just change the functions over.
