If they ban Greninja, you can't use Greninja in OU. If you can't use Greninja in OU, you can't get A-Greninja. So, A-Greninja will also be unusable if Greninja is banned. This is obvious shit, anons.
The only way Protean Greninja alone can be banned, while Battle Bond Greninja stays is if they ban the ability Protean altogether. So no Pokemon can have that ability. That is the only situation in which Protean Greninja will be banned, but A-Greninja stays OU.
