MIPS: SMP: Allow boot_secondary SMP op to return errors
Allow the boot_secondary SMP op to return an error to __cpu_up(), which will in turn return it to its caller. This will allow SMP implementations to return errors quickly in cases they they know have failed, rather than relying upon __cpu_up() eventually timing out waiting for the cpu_running completion.
