usb-storage is a compound device that automatically creates a USB

Replace usb-storage with usb-bot, which can be combined with a manually
created SCSI device. libvirt will configure the SCSI device in a way
identical with how QEMU does for usb-storage except that now it respects
a configuration option to represent CD-ROM.
Is this change compatible for QEMU's VMState aka migration ABI compatible ?
