scsi: atari_scsi: Reset DMA during bus reset only under ST-DMA lock
The atari_scsi driver should not access Falcon DMA chip registers unless it has acquired exclusive access to that chip. If the driver doesn't have exclusive access then there's no need for a DMA reset as there are no scsi commands in progress. Signed-off-by:Finn Thain <fthain@telegraphics.com.au> Tested-by:
