create_gpadl_header() creates a message header, and one or more message bodies if the number of GPADL entries exceeds what fits in the header. Currently the code for creating the message header is duplicated in the two halves of the main "if" statement governing whether message bodies are created. Eliminate the duplication by making minor tweaks to the logic and associated comments. While here, simplify the handling of memory allocation errors, and use umin() instead of open coding it. For ease of review, the indentation of sizable chunks of code is *not* changed. A follow-on patch updates only the indentation. No functional change.

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.
