doc: idmappings: fix an error and rephrase a paragraph
If the modified paragraph is referring to the idmapping mentioned in the
previous paragraph (i.e. `u0:k10000:r10000`), then it is `u0` that the
upper idmapset starts with, not `u1000`.
Fix this error and rephrase this paragraph a bit to make this reference
more explicit.
