Sreekanth Reddy 8071dbe1bd scsi: core: Avoid printing an error if target_alloc() returns -ENXIO ...

[ Upstream commit 70edd2e6f652f67d854981fd67f9ad0f1deaea92 ]

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.
