virt: stats: make disk_rate more robust

Bulk stats can return any subset of keys.
Previously, we had too weak protection, leading
to some KeyError peppering up the logs, for example
when storage was slow to respond.

Now we add more careful protection for disk_rate.
Following patches will fix the other code accessing
storage stats.
