spapr_vscsi: do not allow device hotplug
We do not implement hotplug in the vscsi bus, but we forgot to tell qdev about it. The result is that users are able to hotplug devices in the vscsi bus, the devices appear in qdev, but they aren't usable by the guest OS unless the user reboots it first. Setting qbus hotplug_handler to NULL will tell qdev-monitor, via qbus_is_hotpluggable(), that we do not support hotplug operations in spapr_vscsi.
