You really shouldn't invoke srcu_torture_stats_print() after invoking cleanup_srcu_struct(), but there is really no reason to get a compiler-obfuscated per-CPU-variable NULL pointer dereference as the diagnostic. This commit therefore checks for NULL ->sda and makes a more polite console-message complaint in that case.

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.
