[ Upstream commit 773dc23ff81838b6f74d7fabba5a441cc6a93982 ]
When the client attempts to tree connect to a domain-based DFS namespace from a DFS interlink target, the server will return STATUS_BAD_NETWORK_NAME and the following will appear on dmesg:
CIFS: VFS: BAD_NETWORK_NAME: \dom\dfs
Since a DFS share might contain several DFS interlinks and they expire after 10 minutes, the above message might end up being flooded on dmesg when mounting or accessing them.
Print this only once per share.
