[PATCH] Fix parportbook build again

From: Herbert Xu <herbert@gondor.apana.org.au>

The previous fix causes a syntax error when building:

Working on: /home/gondolin/herbert/src/debian/work/kernel/build/2.6/kernel-source-2.6.5-2.6.5/Documentation/DocBook/parportbook.sgml

jade:/home/gondolin/herbert/src/debian/work/kernel/build/2.6/kernel-source-2.6.5-2.6.5/Documentation/DocBook/parportbook.sgml:4058:0: comment declaration started here

This patch removes the offending line completely since that file is probably
not coming back anyway.
