swift-dispersion-report broken

[gholt]

The swift-dispersion-report seems horribly broken, I believe since the partial replica support was added.

On my development SAIO, I run swift-dispersion-populate, then delete a whole "drive's" worth of data (rm -rf /srv/1/node/sdb1/objects) and then run swift-dispersion-report and get a report like this:

Queried 26 containers for dispersion reporting, 0s, 0 retries
100.00% of container copies found (78 of 78)
Sample represents 10.16% of the container partition space
Queried 25 objects for dispersion reporting, 0s, 0 retries
There were 18 partitions missing -18 copy.
76.00% of object copies found (57 of 75)
Sample represents 9.77% of the object partition space

Note the very odd line of: There were 18 partitions missing -18 copy.
