Btrfs: fix BUG_ON in btrfs_submit_compressed_write
This is similar to btrfs_submit_compressed_read(), if we fail after bio is allocated, then we can use bio_endio() and errors are saved in bio->bi_error. But please note that we don't return errors to its caller because the caller assumes it won't call endio to cleanup on error.
