dm vdo: internalize sysfs-only functions

David Alan Gibert, upstream, wants to remove these functions because they are no longer used in the kernel. But we need them for sysfs, so hide them instead. Cf. commit 2ca99346cd62 ("dm vdo: Remove unused functions") Signed-off-by: Matthew Sakai <[email protected]>
