[SCSI] fusion: spi bus reset when driver loads

Browse Source 
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.
