The index returned by qemuDomainDiskLookupByNodename is the position in
the backing chain rather than the index we report in the XML.
Since with -blockdev they differ now and additionally the disk source
also has an index we need to fix the 'threshold' events we report:
1) If it's the top level image we must always trigger the event without
any suffix as we did until now
2) We must report the correct index
3) We must report the correct index also for the top level image, when
blockdev is used.
This means that we need to potentially emit 2 events, one for the device
without the index and then when blockdev is used and the top level image
has an index we must do it also with the index.
This will fix it for blockdev cases, while also not removing previous
semantics.
