BUG/MEDIUM: config: fix missing initialization in numa_detect_topology()

The error path of the NUMA topology detection introduced in commit
b56a7c89a ("MEDIUM: cfgparse: detect numa and set affinity if needed")
lacks an initialization resulting in possible crashes at boot. No
backport is needed since that was introduced in 2.4-dev.
