There are various callsites in the AppArmor code that use aa_get_newest_*
to obtain a reference, followed by putting a reference during cleanup.
Using the condref variants of these functions allows avoiding taking
refcounts unnecessarily, improving performance. Where they cannot be used
(and the reason for that isn't immediately obvious), add comments documenting
the reason.
