Subject: [PATCH] fs/cifs: correctly to anonymous authentication for the
 NTLM(v2) authentication

commit 1a967d6c9b39c226be1b45f13acd4d8a5ab3dc44 upstream.

Only server which map unknown users to guest will allow
access using a non-null NTLMv2_Response.

For Samba it's the "map to guest = bad user" option.
