of: overlay: do not break notify on NOTIFY_{OK|STOP}
We should not break overlay notifications on NOTIFY_{OK|STOP}
otherwise we might break on the first fragment. We should only stop
notifications if a *real* errno is returned by one of the listeners.
Fixes: a1d19bd4cf1fe ("of: overlay: pr_err from return NOTIFY_OK to overlay apply/remove")
