[PATCH -next] doc: correcting the idmapping mount example

[Hongbo Li]

In step 2, we obtain the kernel id `k1000`. So in next step (step
3), we should translate the `k1000` not `k21000`.

Applied to the vfs.misc branch of the vfs/vfs.git tree.
Patches in the vfs.misc branch should appear in linux-next soon.
