qemu: driver: Remove dead code from qemuDomainSnapshotUpdateDiskSources

dd->src is always allocated in this function as it contains the new
source for the snapshot which is meant to replace the disk source.

The label handling code executed if that source was not present thus is
dead code. Remove it.
