Subject: [PATCH] perf(linter/plugins): faster check for `cwd` (#15301)

Follow-on after #14814. Small perf optimization. `cwd` is either `null` or a string, so use cheaper `=== null` check instead of `??` (which is equivalent to `cwd === null || cwd === undefined`).

Also rename the var, just for brevity.
