autofs-5.0.9 - fix amd entry not found at expire
From: Ian Kent <raven@themaw.net>
Due to the way amd matches keys in its map it's possible that
distinct key entries aren't present in the map.
The indirect mount expire procedure needs to lookup cache entries
for offset mounts in order to get the control file handle needed
to send an expire check to them.
So we need to make sure that when a distinct match isn't found
an expire check is still done. That's OK because the mounts in
the expire list are under the autofs directory so they should
be checked and the ap control file handle can be used for it.
