tex-mode: \bf fontification bug

[Karl Chen]

Synopsis:

    emacs -q /tmp/a.tex

    {\bf test}

    M-x font-lock-fontify-buffer

  error("No match %d in highlight %S" 2 (2 (tex-font-lock-append-prop (quote 
bold)) append))
  font-lock-fontify-keywords-region(1 90 t)
  font-lock-default-fontify-region(1 90 t)
  .
  .

This annoyingly interrupts every time I load a file with \bf.
\bfseries is also fontified incorrectly.

I believe the patch below fixes the bug.
