Subject: [PATCH 09/25] apparmor: fix log failures for all profiles in a set
currently only the profile that is causing the failure is logged. This
makes it more confusing than necessary about which profiles loaded
and which didn't. So make sure to log success and failure messages for
all profiles in the set being loaded.
