Re: [libvirt] [PATCHv2 34/62] qemu: domain: Prepare qemuDomainDiskGetBackendAlias for -blockdev

Pass in the node name as the backend alias when -blockdev is used. As copy-on-read is expressed by a separate -blockdev backing chain member we need to decide which node name to use here. For empty cdroms when using -blockdev there is no backend at all so NULL is returned.
