Make runtime_svc_init() function more robust
- Added some debug assertions checking that the runtime services indexes computed by get_unique_oen() are sane. - Do not print the name of the service when its descriptor is invalid. If the descriptor is corrupted then its name field could be corrupted as well and we would end up reading an arbitrary amount of invalid memory. Change-Id: I16f61065277d01fe1555d5a9cf743f7b52ccaa60
