Correct cinder hacking check numbering

We have a couple of hacking checks that are specific to
Cinder that were written a while back.  Unfortunately, when
they were written the numbering scheme for hacking checks was
not understood.  We used N3xx when we should have used C3xx.

This patch corrects that mistake.
