checkpatch: correct check for kernel parameters doc

Adding a new kernel parameter with documentation makes checkpatch complain

  __setup appears un-documented -- check Documentation/admin-guide/kernel-parameters.rst

The list of kernel parameters has moved to a separate txt file, but
checkpatch has not been updated for this.

Make checkpatch.pl look for the documentation for new kernel parameters
in kernel-parameters.txt instead of kernel-parameters.rst.
