samba: Retain case sensitivity of cifs client

When a client supports extended security but server does not,
and that client, in Flags2 field of smb header indicates that

- it supports extended security negotiation
- it does not support security signatures
- it does not require security signatures

Samba server treats a client as a Vista client.

That turns off case sensitivity and that is a problem for cifs vfs client.

So include remote cifs client along with remote samba client
to not do so otherwise.
