Warning in protover.rs making CI fail.

It looks like a new version of Rust is warning about extraneous parentheses, causing our CI to fail in some cases. Let's fix that.

(This is possibly a duplicate, but I can't find the original.)

Looks good iff CI gets happy.

Reviewer: N/A to ahf

CI is happy. I'm merging this to 0.3.5 and forward so that we have working CI across our branches, and because the fix is trivial.
