net: sched: update action implementations to support flags
Extend struct tc_action with new "tcfa_flags" field. Set the field in tcf_idr_create() function and provide new helper tcf_idr_create_from_flags() that derives 'cpustats' boolean from flags value. Update individual hardware-offloaded actions init() to pass their "flags" argument to new helper in order to skip percpu stats allocation when user requested it through flags.
