iommu/vt-d: Use correct domain id to flush virtual machine domains
For virtual machine domains, domain->id is a virtual id, and the real domain id written into context entry is dynamically allocated. So use the real domain id instead of domain->id when flushing iotlbs for virtual machine domains. Signed-off-by: Jiang Liu <jiang.liu@linux.intel.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
