Multiple cockroachdb-vcheck pods in pending state cause depoyment to fail

Just tried deploying CRDB via the operator and hit an issue which blocked the deployment. The state looked like this:
```
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
cockroach-operator-64fb9fd497-b5gdh 1/1 Running 1 30m
cockroachdb-vcheck-26995099-522cz 0/1 Pending 0 23m
cockroachdb-vcheck-26995101-gkl5j 0/1 Pending 0 21m
cockroachdb-vcheck-26995104-kv8jh 0/1 Pending 0 18m
cockroachdb-vcheck-26995108-k9dq6 0/1 Pending 0 14m
cockroachdb-vcheck-26995116-phdz7 0/1 Completed 0 7m3s
```

After correcting the example.yaml file (I'd spec'd too much CPU/RAM), and they deleting it and re-applying it, I was able to proceed:
```
[mgoddard@MichaelG-MacBook-Pro Bug_Bash_2021.04.29]$ kubectl delete -f example.yaml
crdbcluster.crdb.cockroachlabs.com "cockroachdb" deleted
[mgoddard@MichaelG-MacBook-Pro Bug_Bash_2021.04.29]$ kubectl get pods
NAME READY STATUS RESTARTS AGE
cockroach-operator-64fb9fd497-b5gdh 1/1 Running 1 41m
[mgoddard@MichaelG-MacBook-Pro Bug_Bash_2021.04.29]$ kubectl apply -f example.yaml

```

Apparently, there was one pending vcheck pod per each of my attempts to revise and reapply the YAML.
