Eric Dumazet a01550d778 net_sched: gen_estimator: fix broken estimators based on percpu stats 
[ Upstream commit a5f7add332 ]

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: 1c0d32fde5 ("net_sched: gen_estimator: complete rewrite of rate estimators")
