Nick Mathewson f9f450d688 Also raise the check for 0 circuit ID in created cell.
And add a comment about why conditions that would cause us to drop a
cell should get checked before actions that would cause us to send a
destroy cell.

Spotted by 'cypherpunks'.

And note that these issues have been present since 0.0.8pre1 (commit
0da256ef), where we added a "shutting down" state, and started
responding to all create cells with DESTROY when shutting down.

o Minor bugfixes:
- We now drop CREATE cells for already-existent circuit IDs and
for zero-valued circuit IDs, regardless of other factors that
might otherwise have called for DESTROY cells. Fixes bug 12191;
bugfix on 0.0.8pre1.
