For btrfs_leaf_free_space(), to get leaf data size, we have two way to
get it:
1) leaf->fs_info->nodesize
2) leaf->len
Anyway, we could get rid of @fs_info parameter for
btrfs_leaf_free_space().
And here we choose method 2), as it provides extra benefit to get leaf
free space without initializing a real fs_info.
