Currently the hw action stats update is called from tcf_exts_hw_stats_update, when a tc filter is dumped, and from tcf_action_copy_stats, when a hw action is dumped. However, the tcf_action_copy_stats is also called from tcf_action_dump. As such, the hw action stats update cb is called 3 times for every tc flower filter dump. Move the tc action hw stats update from tcf_action_copy_stats to tcf_dump_walker to update the hw action stats when tc action is dumped.
