Several bug fixes found by tools and fuzzing:
- Incorrect domain passed during replace to ack faults
- Block the access API from using dmabuf
- Missing unlock on error unwind
- Race seeing a partially setup vdevice in the xarray
- Do not allow vdevices to have multiple stream ids in SMMUv3
- Possible UAF if racing faults with domain changes
