[PATCH 1/2] qemu: Add some cpu hotpluggable inforamtion in vm xml when run "virsh setvcpus vm --count <current> --live".

From: xiajidong <xiajidong(a)cmss.chinamobile.com&gt; The optional cpu attribute current can be used to specify whether fewer than the maximum number of virtual CPUs should be enabled. when run "virsh setvcpus vm --count <current> --live", it can display cpu hotpluggable information when run "virsh dumpxml vm | grep vcpu". so we can know the value of enabled and hotpluggable attributes of the current vcpus.
