Add test cases to verify the handling of unsupported input values for the PMU event filter. The tests cover unsupported "action" values, unsupported "flags" values, and unsupported "nevents" values. All these cases should return an error, as they are currently not supported by the filter. Furthermore, the tests also cover the case where setting non-existent fixed counters in the fixed bitmap does not fail.

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.
