ktest: Ignore warnings during reboot
The reboot just wants to get to the next kernel. But if a warning (Call Trace) appears, the monitor will report an error, and the reboot will think something went wrong and power cycle the box, even though we successfully made it to the next kernel. Ignore warnings during the reboot until we get to the next kernel. It will still timeout if we never get to the next kernel and then a power cycle will happen. That's what we want it to do.
