    libxc: allow empty memory nodes in vNUMA
    
    The test for 'nr_vmemranges < nr_vnodes' in xc_domain_setvnuma() was
    originally writtten with the idea that number of memory ranges would
    at least be equal to number of nodes.
    
    We may want to specify nodes with no memory, however, and thus this
    check should be removed.
