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.
