x/benchmarks: cockroachdb failing after CL 564197 (runtime: only poll network from one P at a time in findRunnable)

[prattmic]

As of https://go.dev/cl/564197 (for #65064), all 4 perf builders are failing due to cockroachdb errors.

e.g., https://ci.chromium.org/ui/p/golang/builders/ci/gotip-linux-arm64_c4ah72-perf_vs_release/b8716897839307984241/overview

At the moment, this CL is the most recent run of these builders, so more data will be useful to see if this is consistent. But given that all builders failed, it seems less likely to be a flake.
