MdeModulePkg/UsbMassStorageDxe: Fix USB Mass Storage detection
https://bugzilla.tianocore.org/show_bug.cgi?id=766
Update logic to not return an error from UsbBootRequestSense()
if a Request Sense command responds with no sense information.
It is legal for a USB mass storage device to respond to a
Request Sense command with a SenseKey of
USB_BOOT_SENSE_NO_SENSE and an Additional Sense
Code of USB_BOOT_ASC_NO_ADDITIONAL_SENSE_INFORMATION.
This is described in Section 3.3 of the Universal Serial
Bus Mass Storage Specification For Bootability:
http://www.usb.org/developers/docs/devclass_docs/usb_msc_boot_1.0.pdf
The previous logic returned an error of EFI_NO_RESPONSE
and this caused USB mass storage devices such as a USB
floppy drive to not be detected.
