[libvirt] [PATCH] util: storage: Copy driver type when initializing chain element
virStorageSourceInitChainElement initializes a new storage chain element
for use as a new disk source. If the new element doesn't contain the
driver name, copy it from the old source.
This fixes issue where a disk would forget the driver after a snapshot.
