You could try something like this:

(mapc
 (lambda (b) (set-buffer b) (buffer-update-mode-line))
 (delete-dups
  (mapcar 'window-buffer
          (apply 'append
                 (mapcar 'window-list (frame-list))))))

though if you refactored your buffer-update-mode-line to accept the
buffer as parameter you could write this a bit more elegantly:

(mapc 'buffer-update-mode-line
      (delete-dups
       (mapcar 'window-buffer
               (apply 'append
                      (mapcar 'window-list (frame-list))))))
