To eliminate the use of the page pool fields in struct page, the page pool code should use netmem descriptor and APIs instead. However, __netmem_get_pp() still accesses ->pp via struct page. So change it to use struct netmem_desc instead, since ->pp no longer will be available in struct page. While at it, add a helper, __netmem_to_nmdesc(), that can be used to unsafely get pointer to netmem_desc backing the netmem_ref, only when the netmem_ref is always backed by system memory.

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.
