net: sched: cgroup: verify that filter is not NULL during walk

Check that filter is not NULL before passing it to tcf_walker->fn()
callback in cls_cgroup_walk(). This can happen when cls_cgroup_change()
failed to set first filter.

Fixes: 7e8f8abfb0ed ("net: sched: protect filter_chain list with filter_chain_lock mutex")
