Sarah Sharp f444ff27e9 xhci: STFU: Be quieter during URB submission and completion. 
Unsurprisingly, URBs get submitted and completed a lot in the xHCI
driver.  If we have to print 10 lines of debug for every URB submitted
or completed, then that can cause the whole system to stay in the
interrupt handler too long, and can cause Missed Service completion
codes for isochronous transfers.

Cut down the debugging in the URB submission and completion paths:
 - Don't squawk about successful transfers, only unsuccessful ones.
 - Only print the number of bytes transferred if this was a short
   transfer.
 - Don't print the endpoint index for successful transfers (will add
   more debug to failed transfers to show endpoint index there later).
 - Stop printing MMIO writes.  This debugging shows up when the endpoint
   doorbell is rung a to start a transfer (basically for every URB).
 - Don't print out the ring enqueue and dequeue pointers
 - Stop printing when we're pointing to a link TRB.
