We already have memory in the union here that is being wasted in AMD's case, use it to store the nid. Putting the nid here further isolates the io_pgtable code from the struct protection_domain. Fixup protection_domain_alloc so that the NID from the device is provided, at this point dev is never NULL for AMD so this will now allocate the first table pointer on the correct NUMA node.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
