Some drivers do not provide per-queue statistics. So, there is no point
to have these misleading zeros in xstats.

Really?
It is useful to have zeros rather than random data there.

I guess there is a misunderstanding here. Auto-filling xstats is
an addition of per-queue basic statistics to xstats by ethdev
layer. It makes sense to do it if and only if there is some
sensible data there.

There is a related deprecation notice saying that per-queue
stats should be removed from basic stats since per-queue
stats should be provided by xstats API natively.

Basically RTE_ETH_DEV_AUTOFILL_QUEUE_XSTATS means
that corresponding driver is not ready vs the deprecation notice.
So, I want to clean it up to see not yet ready drivers only.
