Previously, fs.promises.mkdtemp() would cause a TypeError "Method Promise.prototype.then called on incompatible receiver undefined" when called without write permissions. This happened because the promise was never returned to JavaScript after being rejected. This commit ensures SetReturnValue() is called before returning from the function, so JavaScript receives a proper rejected promise with an ERR_ACCESS_DENIED error that can be caught and handled. Fixes: nodejs#59023
