usb: xhci: remove enq_updates and deq_updates from ring
enq_updates and deq_updates were introduced in the first place to check whether an xhci hardware is able to respond to trbs enqueued in the ring. We now have trb tracers to trace every single enqueue/dequeue trb. It's time to remove them and the associated debugging code.
