pc-dimm: Don't check dimm->node when there is non-NUMA config
It should not break memory hotplug feature if there is non-NUMA option. This patch would also allow to use pc-dimm as replacement for initial memory for non-NUMA configs. Note: After this patch, the memory hotplug can work normally for Linux guest OS when there is non-NUMA option and NUMA option. But not support Windows guest OS to hotplug memory with no-NUMA config, actully, it's Windows limitation.
