[Star Wars: Rogue One] Why are members of the Emperor's Royal Guard - Palpatine's personal bodyguards - protecting Lord Vader?

They were used for other things beside just the Emperor's people persoal bodyguards. They were also assassins and protected other high level Imperial personal (like Vader). They were also rotated back into being regular stormtroopers so they would stay militarily sharp. It's kinda like how the secret service guards the president but are also responsible for hunting down counterfeiters.
