iommu/vt-d, trivial: print correct domain id of static identity domain (9544c003) · Commits · 戴 / test

Field si_domain->id is set by iommu_attach_domain(), so we should only print domain id for static identity domain after calling iommu_attach_domain(si_domain, iommu), otherwise it's always zero. Signed-off-by:
