[Patch net v3 2/3] net_sched: fix reference counting of tc filter chain

This patch fixes the following ugliness of tc filter chain refcnt: a) tp proto should hold a refcnt to the chain too. This significantly simplifies the logic. b) Chain 0 is no longer special, it is created with refcnt=1 like any other chains. All the ugliness in tcf_chain_put() can be gone!
