net/sched: use the hardware intermediate representation for matchall
Extends matchall offload to make use of the hardware intermediate representation. More specifically, this patch moves the native TC actions in cls_matchall offload to the newer flow_action representation. This ultimately allows us to avoid a direct dependency on native TC actions for matchall.
