perf: always pass node to revlog.revision()
I removed this in 73c3e226d2fc thinking it wasn't necessary. In fact,
we need to always pass a node so the code is compatible with revisions
before d7d64b89a65c.
The new code uses a variable to avoid check-style complaining
about "r.revision(r.node(" patterns.
