[PATCH] app/testpmd: fix multi-pool Rx setup with --no-NUMA

[Maayan Kashani]

When NUMA is disabled, mbuf pools are allocated on SOCKET_ID_ANY,
but rx_queue_setup() looked them up using port->socket_id. Per-segment
pool lookup failed and all segments fell back to the first pool,
causing Rx queue setup to fail when a later segment needed a larger
mbuf (e.g. --mbuf-size=314,978 --rxpkts=186,978).

Check numa_support inside mbuf_pool_find() and drop the duplicate
NUMA socket remapping from start_port().
