autofs-5.0.1 - fix reconnect get base dn

From: Ian Kent <raven@themaw.net>

If connect to an LDAP server but fail to find a valid query dn a
subsequent reconnect succeeds without setting the schema fields
used for constructing queries. A segfault then occurs when we try
to construct a query using the schema values that should have been
set during the query dn validation.
