scsi: core: Avoid printing an error if target_alloc() returns -ENXIO
Avoid printing a 'target allocation failed' error if the driver target_alloc() callback function returns -ENXIO. This return value indicates that the corresponding H:C:T:L entry is empty. Removing this error reduces the scan time if the user issues SCAN_WILD_CARD scan operation through sysfs parameter on a host with a lot of empty H:C:T:L entries. Avoiding the printk on -ENXIO matches the behavior of the other callback functions during scanning.
