[PATCH v2 3/3] qemuDomainDetachDeviceLive: Handle hostevs with unassigned type of address

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 hotunplug (e.g. never ask QEMU on the monitor to detach the device, or never wait for DEVICE_DELETED event).
