Since papr_scm_ndctl() can be called from outside papr_scm, its exposed to the possibility of receiving NULL as value of 'cmd_rc' argument. This patch updates papr_scm_ndctl() to protect against such possibility by assigning it pointer to a local variable in case cmd_rc == NULL. Finally the patch also updates the 'default' add a debug log unknown 'cmd' values.

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.
