limits API raises TypeError with NoopQuotaDriver

[Matthew Edmonds]

when quota_driver=nova.quota.NoopQuotaDriver in nova.conf, a GET v2/{tenant_id}/limits request fails with HTTP 400 and api.log shows the following stacktrace:

This appears to be because v = -1 for all resources with the NoopQuotaDriver

What version are you running?
I think a fix for this was merged in icehouse-2 and then just recently back-ported to havana.

I was using havana, apparently pre-backport. Marked this as a dup. Thank you.
