iommufd: Use iommufd_access_change_ioas in iommufd_access_destroy_object
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.
