[SCSI] aic94xx SCSI timeout fix
The patch updates DDB0 in the aic94xx driver itself. It doesn't supply or use lldd_port_formed field. DDB0 is updated prior to posting notification to libsas layer. Signed-off-by: Malahal Naineni <malahal@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
