greybus: protocol.c: fix a kernel panic caused by __gb_protocol_register 



__gb_protocol_register check if the protocol is not already registred,
and then register it. It register in existing->lists but at this point,
existing is always NULL (we exist just before if not).
Use gb_protocols instead.
