This change fixes the platform_KernelErrorCodePaths test so that it
does not hang on Tegra2 systems.  On those systems, there is no
'preserved memory' support, so the sysctl settings to cause an
immediate reboot are not set.

The result now is that the test will fail (rather than hang) on Tegra2
boards.  It completes successfully on Mario machines.
