rust-revlog: move check for nodemap requirement to caller
It's good for both making `Revlog` testable and reusable to have it
not depend on the higher-level `Repo` type. This patch is one step in
towards that. Additionally, this change in particular gives the
callers more control over when to use a nodemap.
