Currently we have three QemuOptsList (qemu_common_drive_opts,
qemu_legacy_drive_opts, and qemu_drive_opts), only qemu_drive_opts
is added to vm_config_groups[].
We query commandline options by checking information in
vm_config_groups[], so we can only get a NULL parameter list now.
This patch copied desc items of qemu_legacy_drive_opts and
qemu_common_drive_opts to qemu_drive_opts.
