[PATCH v2] CIFS: don't log STATUS_NOT_FOUND errors for DFS

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

cifs.ko makes DFS queries regardless of the type of the server and
non-DFS servers are common. This often results in superfluous logging of
non-critical errors.

v2: instead of always logging at FYI level, only log non-ENOENT errors
    at VFS level
