        src/sys/dev/usb: ohci.c ohcivar.h

Log Message:
Restructure interrupt handling a little:
* Only futz with the done list in the soft interrupt handler.  In the hard
  interrupt handler, do nothing except mask WDH and queue the soft interrupt.
  This simplifies a bunch of code, removes two O(n^2) queue manipulations,
  and gets rid of some really sketchy stuff around the queue head access.
* Use the auto-masking code at the end of the interrupt handler for both WDH
  and RHSC interrupts.  Again, this reduces the code a little, and avoids
  multiple writebacks to the chip registers.
