apparmor: fix auditing of domain transition failures due to incomplete policy 

When policy specifies a transition to a profile that is not currently
loaded, it result in exec being denied.  However the failure is not being
audited correctly because the audit code is treating this as an allowed
permission and thus not reporting it.
