rust-nodemap: don't compute the error string unless needed This is... really dumb and costs a ton of performance in a hot loop. It was 75% of a profile for a tip to null p1 node traversal in pure Rust. I'm at fault, done in 652149ed64f08ee73e8fd2f76aa480ea8820fe08. I thought clippy had a lint for this, but apparently not?
