virNumaGetPages: Don't fail on huge page-less systems

If we are running on a system that is not capable of huge pages (e.g.
because the kernel is not configured that way) we still try to open
"/sys/kernel/mm/hugepages/" which however does not exist. We should
be tolerant to this specific use case.
