When trying to increse the amount of vCPUs in a VM, we were greeted with a cgroup error: ``` virCgroupSetValueRaw:502 : Unable to write to '/sys/fs/cgroup/machine.slice/.../vcpu6/cpuset.cpus': Numerical result out of range ``` It turns out that when live repinning the VM on the new hypervisor, we were iterating only over the amount of vCPUs assigned to the VM (for example, 0 to 5) instead of the max amount of vCPUs assignable (coming from props.max_cpus). Now we iterate over the max amount of vCPUs assignable and pin them to the local hypervisor topology.

I tested it on machines with two NUMA nodes and machines with single NUMA nodes.
