drm/atomic: Unconfuse the old_state mess in commmit_tail
I totally butcherd the job on typing the kernel-doc for these, and no one realized. Noticed by Russell. Maarten has a more complete approach to this confusion, by making it more explicit what the new/old state is, instead of this magic switching behaviour. v2: - Liviu pointed out that wait_for_fences is even more magic. Leave that as @state, and document @pre_swap better. - While at it, patch in header for the reference section. - Fix spelling issues Russell noticed. v3: Fix up the @pre_swap note (Liviu): Also s/synchronous/blocking/, since async flip is something else than non-blocking.
