The only "invalid" state we can check at the moment is SVEState::Unknown. Which
would translate here to a value of 0 in the register, which isn't incorrect,
it's just pesimistic.
By the time you're printing this register you'd likely have checked the state
fully. Maybe it would come back as SVEState::Disabled, but in that case you
wouldn't have SME anyway so this register isn't available to you.
