Make the aac driver be INTR_MPSAFE. Once the interrupt handler determines
that a command completion happened, all further processing is deferred to
a taskqueue. The taskqueue itself runs implicetely under Giant, but we
already used a taskqueue for the biodone() processing, so this at least
saves the contesting of Giant in the interrupt handler.
