Create virStorageSourceGetBackingStore function in preparation for quorum: Actually, if we want to get a backing store inside a virStorageSource we have to do it manually(src->backingStore = backingStore). The problem is that with a quorum, a virStorageSource can contain multiple backing stores, and src->backingStore can be treated as a virStorageSourcePtr or a virStorageSourcePtrPtr.
Due to these reason, we need to simplify the manipulation of virStorageSource, and create a function to get the asked backingStore in a virStorageSource
For now, this function only return the backingStore field
