net: sched: optimize class dumps
In commit 59cc1f61f09c ("net: sched: convert qdisc linked list to
hashtable") we missed the opportunity to considerably speed up
tc_dump_tclass_root() if a qdisc handle is provided by user.
Instead of iterating all the qdiscs, use qdisc_match_from_root()
to directly get the one we look for.
