dpdk: Be wary of the return value from rte_eth_dev_socket_id
Prior to dpdk-22.11, VPP can count on rte_eth_dev_socket_id to return
numa node 0 if the device didn't set it. Ever since below patch is
committed in dpdk
https://patchwork.dpdk.org/project/dpdk/patch/20220929120512.480-1-olivier.matz@6wind.com/#152498
the aforementioned assumption is no longer true. If the device didn't
set the numa node, VPP gets -1 from the aforementioned API call. This
causes VPP to crash.
This fix is to set the numa node to 0 if the API returns -1, or SOCKET_ID_ANY
Type: fix
