iommu: Set owner token to SVA domain

Commit a9c362d ("iommu: Validate that devices match domains") added
an owner token to the iommu_domain. This token is checked during domain
attachment to RID or PASID through the generic iommu interfaces.

The SVA domains are attached to PASIDs through those iommu interfaces.
Therefore, they require the owner token to be set during allocation.
Otherwise, they fail to attach.

Set the owner token for SVA domains.
