usb: Move short-not-ok handling to the core
After a short-not-ok packet ending short, we should not advance the queue. Move enforcing this to the core, rather then handling it in the hcd code. This may result in the queue now actually containing multiple input packets (which would not happen before), and this requires special handling in combination with pipelining, so disable pipleining for input endpoints (for now).
