s3:smb2 fix Bug 8428 - wrong reply to DHnC (durable handle reconnect)

According to [MS-SMB2] 3.3.5.9.7
(http://msdn.microsoft.com/en-us/library/cc246784%28v=PROT.13%29.aspx),
smbd must reply with NT_STATUS_OBJECT_NAME_NOT_FOUND as it does not
support durable file-handles yet.

I have seen w2k8r2 running xcopy /C ending up in an endless loop
trying to get back the original file handle from smbd sending the same
requests over and over.

Metze, Jeremy, please check!
