struct filename ->refcnt doesn't need to be atomic

... or visible outside of audit, really.  Note that references
held in delayed_filename always have refcount 1, and from the
moment of complete_getname() or equivalent point in getname...()
there is no references to struct filename instance anywhere
that would be visible to other threads.
