[patch net-next 15/20] net: sched: cls_basic: no need to call tcf_exts_change for newly allocated struct

[Jiri Pirko]

From: Jiri Pirko <j...@mellanox.com>

As the f struct was allocated right before basic_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.
