Please forgive my ignorance, but what does spinlock_init do here in 
relation to setting shost->shost_state?

Elsewhere we have scoped_guard(spinlock_irq, shost->host_lock) for 
protecting setting shost->shost_state and this makes sense to me. 
However I am curious what scoped_guard(spinlock_init, ...) does.
