[libvirt] [PATCH 15/24] conf: numa: Always allocate the NUMA config

[Peter Krempa]

Since our formatter now handles well if the config is allocated and not
filled and the parser always frees the definition before parsing we can
safely always-allocate the NUMA config.

This will help in later patches as the parser will be refactored to just
fill the data.
