I don't understand this and it does not sit well with me.

If we are flushing the policy database, we are flushing it
regardless of what the security layer might or might not say.

I would look at this patch differently if there were some
security level key being checked for a match here, which is
an input key to the flush, but that is not what is happening
here as the object is being looked at by itself.
