bug#20895: [patch] lexical binding broke part of sgml-mode.el

[Stephen Berman <stephen.berman@gmx.net>]

The following change broke some functionality in sgml-mode.el:

   commit 84e0b7dad6f1a8e53261f9b96f5a9080fea681a4
   Author: Stefan Monnier <monnier@iro.umontreal.ca>
   Date:   Mon Apr 13 15:51:15 2015 -0400
   [...]
       * lisp/textmodes/sgml-mode.el: Use lexical-binding.

To see the bug, visit an (X)HTML file and insert a tag (`C-c C-t') that
takes an attribute, such `p' or `a'.

The following patch fixes the problems I have encountered, but I'm not
sure if further adjustments are needed, so I'll defer to whoever knows
the code better about whether to commit it as is.

	* sgml-mode.el (sgml-attributes, sgml-value): Make them work with
	lexical binding.
