Just like btrfs_submit_compressed_read(), there are quite some BUG_ON()s
inside btrfs_submit_compressed_write() for the bio submission path.

Fix them using the same method:

- For last bio, just endio the bio
  As in that case, one of the endio function of all these submitted bio
  will be able to free the comprssed_bio

- For half-submitted bio, wait and finish the compressed_bio manually
  In this case, as long as all other bio finishes, we're the only one
  referring the compressed_bio, and can manually finish it.

And that one doesn't apply cleanly as well, which base did you work on?
