The function `font-latex-jit-lock-force-redisplay' is provided by
auctex. This bug was (temporarily) fixed in the auctex repository in
commit 5b5ef6ee.

Here's the commit msg:
    * font-latex.el (font-latex-jit-lock-force-redisplay): Don't rely
    on existing `jit-lock-force-redisplay' because recent bzr Emacs
    broke compatibility changing the number of arguments.  Reported by
    Robert Goldman.

See also bug #14394

The fix was temporary.

Here's the more recent definition of
font-latex-jit-lock-force-redisplay:
(defun font-latex-jit-lock-force-redisplay (buf start end)
  "Compatibility for Emacsen not offering `jit-lock-force-redisplay'."
    ;; The following block is an expansion of `jit-lock-force-redisplay'
    ;; and involved macros taken from CVS Emacs on 2007-04-28.
    (with-current-buffer buf
      (let ((modified (buffer-modified-p)))
	(unwind-protect
	    (let ((buffer-undo-list t)
		  (inhibit-read-only t)
		  (inhibit-point-motion-hooks t)
		  (inhibit-modification-hooks t)
		  deactivate-mark
		  buffer-file-name
		  buffer-file-truename)
	      (put-text-property start end 'fontified t))
	  (unless modified
	    (restore-buffer-modified-p nil))))))

I suggest you update auctex -- but perhaps using the above definition
will be sufficient.
