[SCSI] fusion: spi bus reset when driver loads
This patch is for spi. This issues bus reset when driver loads. Handling cases when initator has negotiated for packetized, and target negotiated for non-packetized; effectly this bus reset is getting both target and initiator on the same sheet of music.
