[patch net-next] net: sched: don't set extack message in case the qdisc will be created

[Jiri Pirko <jiri@resnulli.us>]

From: Jiri Pirko <jiri@mellanox.com>

If the qdisc is not found here, it is going to be created. Therefore,
this is not an error path. Remove the extack message set and don't
confuse user with error message in case the qdisc was created
successfully.
