Yep - there's no way to report an error as such. If you report false, 
that turns into an OPAL_BUSY being returned to Linux and you get polled 
a few ms later. If you report true, that turns into an OPAL_SUCCESS and 
you actually reboot.

Though if the PHB reset is failing, do we catch that and force a full 
IPL at some point?
