Subject: [PATCH] iommu/vt-d: Allocate si_domain in init_dmars()

This seperates the allocation of the si_domain from its
assignment to devices. It makes sure that the iommu=pt case
still works in the kdump kernel, when we have to defer the
assignment of devices to domains to device driver
initialization time.
