autofs-5.0.9 - check for non existent negative entries in lookup_ghost()
From: Ian Kent <raven@themaw.net>
Map entries that have been created in the cache due to a negative lookup
but don't exist in the map source shouldn't have directories created.
In fact map entries that are negative shouldn't have directories created
at all since they should have neen created befor the entry became negative.
