Shung-Hsi Yu deee01acc6 selftests/bpf: Fix raw_tp null handling test 
Commit b2fc4b17fc, backport of upstream commit 838a10bd2e ("bpf:
Augment raw_tp arguments with PTR_MAYBE_NULL"), was missing the changes
to tools/testing/selftests/bpf/progs/raw_tp_null.c, and cause the test
to fail with the following error (see link below for the complete log)

README 

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.
