The char pointers in 'struct cs_dsp_mock_coeff_def' are expected to
point to C strings. They need to be terminated by a null byte.
However the code does not allocate that trailing null byte and only
works if by chance the allocation is followed by such a null byte.
Refactor the repeated string allocation logic into a new helper which
makes sure the terminating null is always present.
It also makes the code more readable.

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.
