net_sched: acquire RTNL in tc_action_net_exit()
I forgot to acquire RTNL in tc_action_net_exit() which leads that action ops->cleanup() is not always called with RTNL. This usually is not a big deal because this function is called after all netns refcnt are gone, but given RTNL protects more than just actions, add it for safety and consistency. Also add an assertion to catch other potential bugs.
