BUG/MINOR: config: fix NUMA topology detection on FreeBSD

In 2.6-dev1, NUMA topology detection was enabled on FreeBSD with commit
f5d48f8b3 ("MEDIUM: cfgparse: numa detect topology on FreeBSD."). But
it suffers from a minor bug which is that it forgets to check for the
number of domains and always emits a confusing warning indicating that
multiple sockets were found while it's not the case.

This can be backported to 2.6.
