Feng Tian 2e9107b87e MdeModulePkg/Sd: update the sd detection logic 
If there is no card presented before power on, there would
have no card change interrupt generated. This is a corner
case which can't be handled by old logic.

The patch is used to move card present detection in the front
of card change interrupt detection.
