There are 3 ways to lookup a volume, only virStorageVolLookupByName needs pool object.

ACK - this is a minimal patch. A nicer patch might be to search by name in all pools, and if an unambiguous name is found, use that volume, but it requires more work, so there's nothing wrong with using this patch in the meantime.
