If we end up removing the module, we'll call "unregister_blockdev()" or whatever, which in turn gets rid of _all_ pages, and that that time we will correctly get rid of buffers. And before you remove the module I see no advantage to have any guarantees of quiescence and removing the buffer heads. I only see extra code that doesn't seem to have any real purpose..
