RH-Commit: [4/4] b581207df4723f8a278452c92cb1b71a207aabe8 (stefanha/centos-stream-qemu-kvm)
qemu_create_cli_devices() should use qmp_device_add() to match the
behavior of the QMP monitor. A comment explained that libvirt changes
implementing strict CLI syntax were needed.
Peter Krempa <pkrempa@redhat.com> has confirmed that modern libvirt uses
the same JSON for -device (CLI) and device_add (QMP). Go ahead and use
qmp_device_add().
