locking/qspinlock: Add comments
I figured we need to document the spin_is_locked() and spin_unlock_wait() constraints somwehere. Ideally 'someone' would rewrite Documentation/atomic_ops.txt and we could find a place in there. But currently that document is stale to the point of hardly being useful.
