freertos: Fix crash when waking task on CPU1 with scheduler disabled

xPendingReadyList[1] was never initialised correctly, so if a task is added to this list (ie by xSemaphoreGiveFromISR()
or similar) while scheduler is disabled, then it causes a null pointer dereference.

Bug produces stack traces similar to:
