libxc: limit cpu values when setting vcpu affinity
When support for pinning more than 64 cpus was added, check for cpu
out-of-range values was removed. This can lead to subsequent
out-of-bounds cpumap array accesses in case the cpu number is higher
than the actual count.
This patch returns the check.
This is CVE-2013-2072 / XSA-56
