storageBackendProbeTarget: Don't fail if backing store can't be parsed
When the backing store of the image can't be parsed virStorageSourceNewFromBacking returns -1. storageBackendProbeTarget then also fails which makes the pool refresh fail or even the storage pool becomes inactive after (re)start of libvirtd. In situations when we can't access the backing store via network we just report the backing store string, thus we can do the same thing for unparsable backing store to prevent the pool from going offline.
