[PATCH v1 5/6] fs/cifs: always use tree name prefix for DFS resolving

[Aurelien Aptel <aaptel-IBi9RG/b67k@public.gmane.org>]

for some reason the tcon used in build_path_from_dentry for that mount
point doesn't have the the "IN DFS" flag set so the prefix was not
always added even though it is required in this case.
