[SCSI] fusion - Greater than 255 target and lun support
Add support for greater than 255 target and luns. Kill the hd->Target[] field, and change all references of bus_id/target_id, to channel/id. Signed-off-by: Eric Moore <Eric.Moore@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
