smb: client: fix DFS failover in multiuser mounts
For sessions and tcons created on behalf of new users accessing a
multiuser mount, matching their sessions in tcon_super_cb() with
master tcon will always lead to false as every new user will have its
own session and tcon.
All multiuser sessions, however, will inherit ->dfs_root_ses from
master tcon, so match it instead.
