smb3: move Documentation/filesystems/cifs to Documentation/filesystems/smb

Documentation/filesystems/cifs contains both server and client information
so its pathname is misleading.  In addition, the directory fs/smb
now contains both server and client, so move Documentation/filesystems/cifs
to Documentation/filesystems/smb
