Florian Westphal 7cd3fee7b3 netfilter: nf_tables: remove register tracking infrastructure
[ Upstream commit 6b94d081f8 ]

This facility was disabled in commit
9e539c5b6d ("netfilter: nf_tables: disable expression reduction infra"),
because not all nft_exprs guarantee they will update the destination
register: some may set NFT_BREAK instead to cancel evaluation of the
rule.

This has been dead code ever since.
There are no plans to salvage this at this time, so remove this.

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 Restructured Text 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.
