A <hostdev/> can have <address type='unassigned'/> which means
libvirt manages the device detach from/reattach to the host but
the device is never exposed to the guest. This means that we have
to take a shortcut during hotplug, similar to the one we are
taking when constructing the command line (see
qemuBuildHostdevCommandLine()).
