Feng Tian 17f3e942bc MdeModulePkg/UsbMass: Not retry if usb bot transfer execution fail
The retry mechanism will bring issue if the usb device is unplugged
from XHCI HC but s/w is trying to access it through BlockIo. The
current cmd will get device error return status, but the sequential
cmds will be timeout. This behavior will cause system unresponsive
for a long while and bring bad user experience.

So we break the retry loop if found device error.
