of: unittest: Remove error printing on OOM
There is no need to print a backtrace or other error message if kzalloc(), kmemdup(), or devm_kzalloc() fails, as the memory allocation core already takes care of that. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Rob Herring <robh@kernel.org>
