dmatest: add dma interrupts and callbacks

Use the callback infrastructure to report driver/hardware hangs or
missed interrupts.  Since this makes the test threads much more
aggressive (from: explicit 1ms sleep to: wait_for_completion) we set the
nice value to 10 so as to not swamp legitimate tasks.
