USB: new quirk flag to avoid Set-Interface
This patch (as1057) fixes a problem with the X-Rite/Gretag-Macbeth
Eye-One Pro display colorimeter; the device crashes when it receives a
Set-Interface request. A new quirk (USB_QUIRK_NO_SET_INTF) is
introduced and a quirks entry is created for this device.
