[PATCH] app/testpmd: reserve NUMA node per device port and per ring

[PATCH] app/testpmd: reserve NUMA node per device port and per ring

[Phil Yang]

If user explicitly requested memory to be allocated from a socket via
`port-numa-config` and `rxring-numa-config`, and if that socket is
valid, add that socket into socket_ids[] so that mempool allocated for
that socket.

Fixes: dbfb8ec ("app/testpmd: optimize mbuf pool allocation")
