btrfs_super_total_bytes is total size of all devices. we can't rely on it as
search_end for two reasons:
1) If metadata mirror is enable, the value can be larger than the last byte of
last chunk.
2) For a FS has been balanced, there are some 'holes' in the chunk address
space, so the value can be smaller than the last byte of last chunk.
