After commitf42ee093be("bpf/test_run: support cgroup local storage") the bpf_test_run() function may fail with -ENOMEM, if it's not possible to allocate memory for a cgroup local storage. This error shouldn't be mixed with the return value of the testing program. Let's add an additional argument with a pointer where to store the testing program's result; and make bpf_test_run() return either 0 or -ENOMEM.

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.
