  ethdev: specify return value of xstats-get API
  ethdev: optimize xstats-get API's implementation
  net/hns3: adjust return value of xstats-get ops
  net/ipn3ke: adjust return value of xstats-get ops
  net/mvpp2: adjust return value of xstats-get ops
  net/axgbe: adjust return value of xstats-get ops
  ethdev: fix memory leak when telemetry xstats
  ethdev: fix possible null pointer access
  net/cnxk: fix telemetry possible null pointer access

v4:
* refine the return value definitions of rte_eth_xstats_get() and
  the implementation of related drivers is corrected.
* drop auto-filled flag patch.
v3:
* refine the descriptor of return value when xstats is null of
