Gocbv2 CCCP poller after PUT /{db}/ for an invalid bucket never stops

The gocb retry loop/CCCP polller never stops trying to open a bucket after attemping to create a database with an invalid bucket name.

Repro:

1. Start up SG in persistent mode, no buckets/databases
2. Attempt to create a database with a bucket name that does not exist
3. See create database request fail as expected:
