xhci: Don't trace ring at every enqueue or dequeue increase
Don't trace ring pointers every time driver increases enqueue pointer after queuing a TRB, or dequeue pointer after handling an event. These xhci_inc_deq: and xhci_inc_enq: trace entries fill up the trace and provides little useful info now that the TRB DMA address is printed with the TRB itself. Only trace ring during xhci_inc_enq() and xhci_inc_deq() in case we move to a new ring segment. Also don't show both segment and TRB addess in trace. Segment is just TRB with 0xfff masked off.
