net: sched: route: don't set arg->stop in route4_walk() when empty
Some classifiers set arg->stop in their implementation of tp->walk() API
when empty. Most of classifiers do not adhere to that convention. Do not
set arg->stop in route4_walk() to unify tp->walk() behavior among
classifier implementations.
Fixes: ed76f5edccc9 ("net: sched: protect filter_chain list with filter_chain_lock mutex")
