amd/iommu: Preserve domain ids inside the kdump kernel
Currently AMD IOMMU driver does not reserve domain ids programmed in the
DTE while reusing the device table inside kdump kernel. This can cause
reallocation of these domain ids for newer domains that are created by
the kdump kernel, which can lead to potential IO_PAGE_FAULTs
Hence reserve these ids inside pdom_ids.
Fixes: 38e5f33ee359 ("iommu/amd: Reuse device table for kdump")
