virsh: vcpuinfo: Report proper vcpu numbers and data for offline VMs
If the VM is offline virsh attempted to at least report the pinning
information for the VM. This would not work properly now that the vcpus
can be sparse. Fix it by getting the vcpu states from the XML.
Verified this issue and get the expected result.
