If a USB Mass Storage device does not support the Get
Max LUN command, then the USB I/O Protocol ControlTransfer()
service may return an error. If an error is returned for
this command, then assume that the device does not support
multiple LUNs and return a maximum LUN value of 0.
The USB Mass Storage Class Specification states that a
maximum LUN value larger than 0x0F is invalid. Add
a check to make sure this maximum LUN value is in this
valid range, and if it is not, then assume that the
device does not support multiple LUNs and return a
maximum LUN value of 0.
This change improves compatibility with USB FLASH drives
that do not support the Get Max LUN command or return
an invalid maximum LUN value.

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.

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.
