[libvirt] [PATCH] qemu: domain: update only newly detected images in qemuDomainDetermineDiskChain

[Peter Krempa]

The processing code which prepares images should be executed really only
for the images which were detected. The code actually tried to update
the last user-specified layer as well. Thankfully we don't do anything
that would be a problem at this point.
