apparmor: fix replacement bug that adds new child to old parent
When set atomic replacement is used and the parent is updated before the child, and the child did not exist in the old parent so there is no direct replacement then the new child is incorrectly added to the old parent. This results in the new parent not having the child(ren) that it should and the old parent when being destroyed asserting the following error. AppArmor: policy_destroy: internal error, policy '<profile/name>' still contains profiles Signed-off-by: John Johansen <john.johansen@canonical.com> Acked-by: Seth Arnold <seth.arnold@canonical.com>
