qemu: hotplug: Detect disk backing images before setting up security access

Browse Source 
The VM will require access also to the detected images. Unfortunately a
recent reordering of the code introduced a bug where the backing chain
was probed after setting up cgroups/selinux/namespaces, which caused
that any detected images were not allowed/added and qemu was then not
able to use them.
