MINOR: cpuset: add NUMA node identification to CPUs on FreeBSD

Browse Source 
With this patch we're also NUMA node IDs to each CPU when the info is
found. The code is highly inspired from the one in commit f5d48f8b3
("MEDIUM: cfgparse: numa detect topology on FreeBSD."), the difference
being that we're just setting the value in ha_cpu_topo[].
