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
