net_sched: gen_estimator: fix broken estimators based on percpu stats
pfifo_fast got percpu stats lately, uncovering a bug I introduced last
year in linux-4.10.
I missed the fact that we have to clear our temporary storage
before calling __gnet_stats_copy_basic() in the case of percpu stats.
Without this fix, rate estimators (tc qd replace dev xxx root est 1sec
4sec pfifo_fast) are utterly broken.
Fixes: 1c0d32fde5bd ("net_sched: gen_estimator: complete rewrite of rate estimators")
