iommu/vt-d: Fix dereference of pointer info before it is null checked
The assignment of iommu from info->iommu occurs before info is null checked
hence leading to a potential null pointer dereference issue. Fix this by
assigning iommu and checking if iommu is null after null checking info.
Addresses-Coverity: ("Dereference before null check")
