There is no need to check the return value of a debugfs_create_file call, a caller should never change what they do depending on if debugfs is working properly or not, so remove the checks, simplifying the logic in the file a lot. Also fix up the error check for debugfs_create_dir() which was not returning NULL for an error, but rather a error pointer.

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.
