fix CSIT broken issue when numa_node value is -1 on single Socket platform
Single Socket platform e.g. Intel Atom cpu based SOC platform with
Ubuntu 16.04.4(kernel 4.13.0-36-generic) or Centos 7.5 (kernel 3.10.0-862.el7),
value of /sys/bus/pci/devices/<pci_device_id>/numa_node is -1, this will
break CSIT performance test running, but for this kind of SOC platform,
it can consider that is not NUMA based platform, numa_node=-1 is reasonable,
so fix it at CSIT side, when numa_node=1 and the system's NUMA node count
is 1, set numa_node=0. DPDK also did it as this way.
