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.
