The USB-specific cgroup setup had been inserted inline in qemuDomainAttachHostUsbDevice and qemuSetupCgroup, but now there is a common cgroup setup function called for all hostdevs, so it makes sens to put the usb-specific setup there and just rely on that function being called. The one thing I'm uncertain of here (and a reason for not pushing until after release) is that previously hostdev->missing was checked only when starting a domain (and cgroup setup for the device skipped if missing was true), but with this consolidation, it is now checked in the case of hotplug as well. I don't know if this will have any practical effect (does it make sense to hotplug a "missing" usb device?)
