[PATCH 02/12] next-cube.c: don't pulse SCSI DMA IRQ upon reception of FLUSH command |

Normally a DMA FLUSH command is used to ensure that data is completely written
to the device and/or memory, so remove the pulse of the SCSI DMA IRQ if a DMA
FLUSH command is received. This enables the NeXT ROM monitor to start to load
from a SCSI disk.
