[PATCH] (2.6.0-test6-bk) DocBook: Kernel-api build fix

Witht he EXPORT_SYMBOL cleanups, net/netsyms.c has been removed.  The
kernel-api DocBook docs still refer to this file, and because this file
is gone, "make htmldocs" and similar fails.

This just removes the reference and so fixes this docbook problem.
