btrfs: move the bi_sector assignment out of btrfs_add_compressed_bio_pages
Adding pages to a bio has nothing to do with the sector. Move the assignment to the two callers in preparation for cleaning up btrfs_add_compressed_bio_pages. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
