In check_pfn_span(), a 'reason' string is being used to recreate the caller function name, while printing the warning message. It is really unnecessary as the warning message could just be printed inside the caller depending on the return code. Currently there are just two callers for check_pfn_span() i.e __add_pages() and __remove_pages(). Let's clean this up.

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.
