  Many user (e.g. telemetry) invokes rte_eth_xstats_get(port_id, NULL, 0)
to retrieve the required number of elements, but currently ipn3ke PMD
returns zero when xstats is NULL.

In the previous patch, the framework defines that the required number
of entries should be returned when xstats is NULL and n is zero. And
xstats is NULL if and only if n is zero.

Based on the preceding constraints, this patch removes the logic of
"return zero when xstats is NULL".
