Cactus: Return -1 when initialisation fails
According to the SP_EVENT_COMPLETE specification, the secure partition
can either return:
- 0 to indicate it has successfully initialized;
- A negative value to indicate an error;
- A positive value to pass a specific Event Status code.
Therefore, returning 1 in case of error violates the specification.
This patch changes it to -1.
