[PATCH net-next 03/22] net: sched: act_connmark: get rid of tcf_connmark_walker and tcf_connmark_search

[Zhengchao Shao]

Use __tcf_generic_walker() and __tcf_idr_search() helpers by saving
connmark_net_id when registering act_connmark_ops. And then remove
the walk and lookup hook functions in act_connmark.
