Bug#422149: autofs-ldap hangs for 30 seconds with action on a missing directory

[Vince Busam]

Package: autofs-ldap
Version: 4.1.4+debian-1

When attempting to open a file on a missing ldap automount directory, 
autofs will hang for 30 seconds before returning error.  This can be 
recreated on a system with /home automounted via ldap with
cat /home/.missing/badfile
The attached patch resolves the issue.
