Rollup merge of #132395 - Zalathar:coverage-cx-ice, r=jieyouxu
coverage: Avoid ICE when `coverage_cx` is unexpectedly unavailable

In #132124, `coverage_cx()` was changed to panic if the context was unavailable, under the assumption that it would always be available whenever coverage instrumentation is enabled.

However, there have been reports of this change causing ICEs in `polars` CI.

I don't yet understand why this is happening, but for now it seems wisest to revert that part of the change, restoring the two early returns that had been replaced with panics.
