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.
