[libvirt] [PATCH 1/5] virDomainNumaGetNodeDistance: Fix input arguments validation

[Michal Privoznik]

There's no point in checking if numa->mem_nodes[node].ndistances
is set if we check for numa->mem_nodes[node].distances. However,
it makes sense to check if the sibling node caller passed falls
within boundaries.
