Subject: [PATCH] [idd] helper: defer no GPU notification when needed

No GPU notifications are not possible before the notification icon is
created. Since the helper could start before explorer.exe (and often does
on reboot), the notification would fail.

This commit adds logic to refer the notification and we send it immediately
when successfully creating the notification icon.
