fix(longhorn): Fix post-render kustomization

This patch removes one of the adjustments, in order to fix an error
message complaining about not being able to find the resource that is
supposed to be fixed.

```
Helm install failed: error while running post render on files: no matches for Id apps_v1_Deployment|~X|longhorn-driver-deployer; failed to find unique target for patch apps_v1_Deployment|longhorn-driver-deployer
```

I'm not sure why it fails, but this is an attempt to fix it, by removing
the errorous patch. Hopefully the daemonset patching will work out.
