When the cpu is created, qemu_add_vm_change_state_handler
is called in the kvm_arch_init_vcpu function to create
the VMChangeStateEntry resource.
However, the resource is not released when the cpu is destroyed.
This results in a qemu process segment error when the virtual
machine restarts after the cpu is unplugged.
This patch solves the problem by adding the corresponding resource
release process to the kvm_arch_destroy_vcpu function.
