add all the namespaces to the controller inside the CreateNvmeController call

from @benlwalker comment https://github.com/opiproject/opi-marvell-bridge/pull/20#issuecomment-1319043933
```
Technically, a user could do this sequence of steps:

Create subsystem
Create namespace
Create controller
In this case, it needs to go add all the namespaces to the controller inside the CreateNvmeController call.
