Bug fix: handles disk device used multiple times
There were issues in having the same underlying device being referenced
multiple times (via different paths) when reporting storage I/O
statistics. As an example: having two (or more) LVM2/DM volumes crafted
out of the same MD array.
This patch simply skips over any devices previously seen.
