ipe: return -ESTALE instead of -EINVAL on update when new policy has a lower version
When loading policies in userspace we want a recognizable error when an
update attempts to use an old policy, as that is an error that needs
to be treated differently from an invalid policy. Use -ESTALE as it is
clear enough for an update mechanism.
