scsi: core: Avoid printing an error if target_alloc() returns -ENXIO
[ Upstream commit 70edd2e6f6
]
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.
