smb: move client and server files to common directory fs/smb

commit 38c8a9a52082579090e34c033d439ed2cd1a462d upstream.

Move CIFS/SMB3 related client and server files (cifs.ko and ksmbd.ko
and helper modules) to new fs/smb subdirectory:

   fs/cifs --> fs/smb/client
   fs/ksmbd --> fs/smb/server
   fs/smbfs_common --> fs/smb/common

[ added to stable trees to handle the directory change to handle the
  future stable patches due to the constant churn in this filesystem at
  the moment - gregkh ]
