Public bug reported:

This is the Cinder twin to bug 1370869 which was resolved for Nova. For
some yet-to-be-fully-debugged reasons, after deleting multiple instances
the quota_usages table for Cinder ended up with negative values for
several of the "in use" limits, causing the Overview Page to fail with
an error 500:

OverflowError at /project/
cannot convert float infinity to integer

Even if this is (probably?) a rare occurrence, it would make sense to
also add guards for the cinder limits and make the overview page more
resilient.
