Jens Axboe 8c4db3355b backing-dev: bdi sb prune should be in the unregister path, not destroy ...

Commit 592b09a42f was different from
the tested path, in that it moved the bdi super_block prune from
unregister to destroy context. This doesn't fully fix the sync hang
bug on unexpected device removal, as need to prune the bdi cache
pointer before killing flusher thread.
