sound: usb-audio: make the MotU Fastlane work again
commit 55de5ef970c680d8d75f2a9aa7e4f172140dbd9c upstream.
Kernel 2.6.18 broke the MotU Fastlane, which uses duplicate endpoint
numbers in a manner that is not only illegal but also confuses the
kernel's endpoint descriptor caching mechanism. To work around this, we
have to add a separate usb_set_interface() call to guide the USB core to
the correct descriptors.
