Leafsize is deprecated for a long time, and kernel has already updated
ctree.h to rename sb->leafsize to sb->__unused_leafsize.
This patch will remove normal users of leafsize:
1) Remove leafsize member from btrfs_root structure
Now only root->nodesize and root->sectorisze.
No longer root->leafsize.
2) Remove @leafsize parameter from btrfs_setup_root() function
Since no root->leafsize, no need for @leafsize parameter.
The remaining user of leafsize will be:
1) btrfs inspect-internal dump-super
Reformat the "leafsize" output to "leafsize (deprecated)" and
use le32_to_cpu() to do the cast manually.
2) mkfs
We still need to set sb->__unused_leafsize to nodesize.
Do the manual cast too.
3) convert
Same as mkfs, these two superblock setup should be merged later

Without validation of array_size, the dump-super may lead to a bad
memory access.

Some tools (check, select-super, dump-super) can use the alternate
superblocks, but the options are not consistent. To make it less
confusing, change the meaning of option -s in 'dump-super' to specify
the superblock copy, instead of taking the offset.
Though this is a change in UI, the old usage is detected and the result
would be the same, no breakage in existing scripts.

The helper btrfs_super_csum_size unconditionally bugs on a bogus value,
the dump-super is supposed to dump even corrupted superblocks so this
must not happen here. Group the checsum values in the output and be more
robust agains garbage values.

The long-term plan is to merge the features of standalone tools
into the btrfs binary, reducing the number of shipped binaries.
