docbook: fix escaping of kernel-doc

hoi :)

the following patch fixes a bug I introduced with the last patches of the DocBook generation.

---
Please apply.

... and I really have to redo my bitkeeper repository as it is full of merge artifacts as BK did not note the fact that the patches were applied using normal patches.

I guess I have to use one complete tree per patch and recreate the public repo as a combination of the individual ones. Alternatives?

Normally bk would handle that, but I have an irritating habit of stripping off all the trailing whitespace which people keep trying to add to the kernel.

Export all the csets as unified diffs, reapply them.
