Address potential issue with frontend profile editing

Check whether global `$pagenow` has a value before relying on it. Since the hook is called using `admin_init`, I'm not sure exactly how the user has reached this code, but it's possible it could be called manually or via AJAX.

It's not a problem to check for it and to use the alternative code suggested by @shivchawla
