[patch 09/23] [PATCH] [NETFILTER] nf_queue: Fix Ooops when no queue handler registered

[Chris Wright <chrisw@osdl.org>]

-stable review patch.  If anyone has any objections, please let us know.
------------------

With the new nf_queue generalization in 2.6.14, we've introduced a bug
that causes an oops as soon as a packet is queued but no queue handler
registered.  This patch fixes it.
