John Johansen be79d7fa43 apparmor: fix change_hat not finding hat after policy replacement
commit 3d40658c977769ce2138f286cf131537bf68bdfe upstream.

After a policy replacement, the task cred may be out of date and need
to be updated. However change_hat is using the stale profiles from
the out of date cred resulting in either: a stale profile being applied
or, incorrect failure when searching for a hat profile as it has been
migrated to the new parent profile.

Fixes: 01e2b670aa (failure to find hat)
Fixes: 898127c34e (stale policy being applied)
