Dandan Bi f316a26013 MdeModulePkg: Avoid key notification called more than once
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=996

Issue:
In current code logic, when a key is pressed, it will search
the whole NotifyList to find whether a notification has been
registered with the keystroke. if yes, it will en-queue the
key for notification execution later. And now if different
notification functions have been registered with the same key,
then the key will be en-queued more than once. Then it will
cause the notification executed more than once.

This patch is to enhance the code logic to fix this issue.
