net: sched: remove tcf_proto from ematch calls
This removes the tcf_proto argument from the ematch code paths that only need it to reference the net namespace. This allows simplifying qdisc code paths especially when we need to tear down the ematch from an RCU callback. In this case we can not guarentee that the tcf_proto structure is still valid.
