[PATCH 1/2] btrfs-progs: unexport csum_tree_block()

[Qu Wenruo <wqu@suse.com>]

The function csum_tree_block() is not really utilized by anyone, all
current callers just use csum_tree_block_size().

Furthermore there is a stale definition in common/utils.h which is using
the old "struct btrfs_root" as the first argument, while we have already
migrated to "struct btrfs_fs_info".

So just unexport csum_tree_block() and remove the stale definition.
