[libvirt] [PATCH 4/7] qemu: Use virStorageSourceIsEmpty in qemuDomainBlockCommit
The block commit API checked 'disk->src->path' to see whether there
is a reasonable disk source to be committed. As the top image can be
e.g. backed by NBD the check is not good enough. Replace it by
virStorageSourceIsEmpty.
