regcache: flat: Remove unneeded check and error message for -ENOMEM
There is a convention in the kernel to avoid error messages
in the cases of -ENOMEM errors. Besides that, the idea behind
using struct_size() and other macros from overflow.h is
to saturate the size that the following allocation call will
definitely fail, hence the check and the error messaging added
in regcache_flat_init() are redundant. Remove them.

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 reStructuredText 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.
