qemu: hotplug: Update disk private data after hotplug

Browse Source 
The disk private data contain information about the tray and
removability of the disk. Until recently we didn't support hotplug of
removable disks thus it wasn't a problem but now when you can hotplug a
CDROM you would not be able to open its tray.

Fix it by updating the hotplugged disk the same way we do at startup.
