ncr5380: Always escalate bad target time-out in NCR5380_select()
Remove the restart_select and targets_present variables introduced in Linux v1.1.38. The former was used only for a questionable debug printk and the latter "so we can call a select failure a retryable condition". Well, retrying select failure in general is a different problem to a target that doesn't assert BSY. We need to handle these two cases differently; the latter case can be left to the SCSI ML.
