https://bugzilla.tianocore.org/show_bug.cgi?id=767 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.
