net: sched: act: handle extack in tcf_generic_walker
This patch adds extack handling for a common used TC act function "tcf_generic_walker()" to add an extack message on failures. The tcf_generic_walker() function can fail if get a invalid command different than DEL and GET. The naming "action" here is wrong, the correct naming would be command.
