fs validatePath throws instead of calling error callback

• Version: 10.16.3, 12.11.1
• Platform: Windows 64, 32-bit
• Subsystem: fs (utils.js)

This is a regression from node 8.16.2

  const pathname = join(__dirname, "?\0"); // null character will fail validation
  let output = createWriteStream(pathname)
    .on("error", (error) => {
      // do something
  });

validatePath function throws an exception instead of calling error callback

In node 8, the callback was checked

See #18308, that change was introduced deliberately as a semver-major (i.e., backwards incompatible) change.
