Since the commit b4adfe8e05f1 ("locking/lockdep: Remove unused argument
in __lock_release"), @nested is no longer used in lock_release(), so
remove it from all lock_release() calls and friends.

Although this looks fine to me at a first glance, it might be slightly
easier to manage if you hit {spin,rwlock,seqcount,mutex,rwsem}_release()
first with coccinelle scripts, and then hack lock_release() as a final
patch. That way it's easy to regenerate things if needed.

I am not sure if it worth the extra efforts where I have to retest it on all
architectures, and the patch is really simple, but I can certainly do that if
you insist.

I have just confirmed the patch [1] also applied correctly to the latest
mainline, so it might be the best time just for Linus to merge it directly so it
does not introduce build errors later on?
