[PATCH 1/5] virCapabilitiesHostNUMAFormat: Swap order of arguments

[Michal Privoznik]

The rest of virCapabilities format functions take virBuffer as
the first argument and struct to format as the second. Also, they
accept NULL (as the second argument). Fix
virCapabilitiesHostNUMAFormat() so that it follows this logic.
