[libvirt] [PATCHv3 25/26] qemu: blockcopy: Use the mirror disk source to label the files

[Peter Krempa]

Use the source struct and the corresponding function so that we can
avoid using the path separately. Now that
qemuDomainPrepareDiskChainElementPath isn't use anywhere, we can safely
remove it.

Additionally, the removal fixes a misaligned comment as the removed
function was added under a comment for a different function.
