Technically, there's nothing libnuma specific about
virNumaNodesetToCPUset(). It just implements a generic algorithm
over virNumaGetNodeCPUs() (which is then libnuma dependant).
Nevertheless, there's no need to have this function living inside
WITH_NUMACTL block. Any error returned from virNumaGetNodeCPUs()
(including the one that !WITH_NUMACTL stub returns) is propagated
properly.

Move the function out of the block into a generic one and drop
the !WITH_NUMACTL stub.
