net_sched: remove unnecessary ops->delete()
All ops->delete() wants is getting the tn->idrinfo, but we already have tc_action before calling ops->delete(), and tc_action has a pointer ->idrinfo. More importantly, each type of action does the same thing, that is, just calling tcf_idr_delete_index(). So it can be just removed.
