net: sched: cls_matchall: no need to call tcf_exts_change for newly allocated struct
As the head struct was allocated right before mall_set_parms call, no need to use tcf_exts_change to do atomic change, and we can just fill-up the unused exts struct directly by tcf_exts_validate. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
