MdeModulePkg/UsbMass: Revert changes of removing retry logic 

This patch is used to revert changes done in commit 17f3e942
bc527fbd75068d2d5752b6af54917487 - "MdeModulePkg/UsbMass: Not
retry if usb bot transfer execution fail"

It's because Usb Floppy will report DEVICE_ERROR for the first
several cmds when it need spin up. so retry logic makes sense.
