[libvirt] numad: Convert node list to cpumap before affinity setting

[Osier Yang <jyang redhat com>]

Previous patches on numad made mistake with thinking numad
will return CPUs list (numad document says CPUs list one
place, and node list another place. :(

Please see the patches' commit message for the details.
