Cannot migrate vm with local storage datadisk whe using automatic assign

### problem

A vm that has a local storage data disk cannot be migrated without specifying a specific host and results in the message below:
```
Migration failed.
Unable to find suitable destination to migrate VM i-2-6-VM
```
When selecting a specific host the same vm can be migrated.

This also affects maintenance mode as a host that has a vm with local storage datadisk present cannot migrate that vm, see #9887.
