Subject: [PATCH] qemuDomainVirStorageSourceFindByNodeName: Match also
 '<dataStore>' sources

As the source for the data file is a completely separate
virStorageSource including it's own index we need to match it
explicitly, so that code such as storage threshold events work properly
and separately for the data file.
