Re: [PATCH] virnuma: Report error when NUMA -> CPUs translation fails

When starting a domain with <numatune/> set libvirt translates given NUMA nodes into a set of host CPUs which is then used to QEMU process affinity. But, if the numatune contains a non-existent NUMA node then the translation fails with no error reported. This is because virNumaNodesetToCPUset() calls virNumaGetNodeCPUs() and expects it to report an error on failure. Well, it does except for non-existent NUMA nodes. While this behaviour might look strange it is actually desired because of how we construct host capabilities. The virNumaGetNodeCPUs() is called from virCapabilitiesHostNUMAInitReal() where we do not want any error reported for non-existent NUMA nodes.
