Tom Rix 9f5cab173e module: remove use of uninitialized variable len
clang build reports
kernel/module/stats.c:307:34: error: variable
  'len' is uninitialized when used here [-Werror,-Wuninitialized]
        len = scnprintf(buf + 0, size - len,
                                        ^~~
At the start of this sequence, neither the '+ 0', nor the '- len' are needed.
So remove them and fix using 'len' uninitalized.

Fixes: df3e764d8e ("module: add debug stats to help identify memory pressure")

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.
