I didn't check this, but could you do this instead? 
(I use this form of define-keymap in other cases.)

(defun tab-line--undefine-keys ()
  "Uninstall key bindings previously bound by `tab-line--define-keys'."
  (when tab-line-define-keys
    (define-keymap :keymap ctl-x-map
      [left] 'previous-buffer
      [C-left] 'previous-buffer
      [M-left] nil
      [right] 'next-buffer
      [C-right] 'next-buffer
      [M-right] 'next-buffer)))
