iommu/vt-d: Remove DEFER_DEVICE_DOMAIN_INFO
Allocate and set the per-device iommu private data during iommu device
probe. This makes the per-device iommu private data always available
during iommu_probe_device() and iommu_release_device(). With this changed,
the dummy DEFER_DEVICE_DOMAIN_INFO pointer could be removed. The wrappers
for getting the private data and domain are also cleaned.
