[PATCH v7 RESEND 09/12] iommu: Assign the direct mapped domain to group->domain

[Baoquan He]

In iommu_request_dm_for_dev(), devices of group have all been attached
to newly created direct mapped domain. We should store the domain into
group->domain so that it works for iommu_get_domain_for_dev() and
get_domain().
