net_sched: remove list_head from tc_action
After commit 90b73b77d08e, list_head is no longer needed. Now we just need to convert the list iteration to array iteration for drivers. Fixes: 90b73b77d08e ("net: sched: change action API to use array of pointers to actions") Cc: Jiri Pirko <jiri@mellanox.com> Cc: Vlad Buslov <vladbu@mellanox.com> Signed-off-by: Cong Wang <xiyou.wangcong@gmail.com> Signed-off-by: David S.
