Update iommufd_access_destroy_object() to call the new iommufd_access_change_ioas() helper. It is impossible to legitimately race iommufd_access_destroy_object() with iommufd_access_change_ioas() as iommufd_access_destroy_object() is only called once the refcount reache zero, so any concurrent iommufd_access_change_ioas() is already UAFing the memory.
