Minoru Usui 52ea3a56a3 cls_cgroup: Fix oops when user send improperly 'tc filter add' request 
I found a bug in cls_cgroup_change() in cls_cgroup.c.
cls_cgroup_change() expected tca[TCA_OPTIONS] was set from user space properly,
but tc in iproute2-2.6.29-1 (which I used) didn't set it.

In the current source code of tc in git, it set tca[TCA_OPTIONS].

  git://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git

If we always use a newest iproute2 in git when we use cls_cgroup, 
we don't face this oops probably.
But I think, kernel shouldn't panic regardless of use program's behaviour.
