Don't print 'target allocation failed' message if the driver
returns -ENXIO error value for target_alloc callback function.
Driver returns -ENXIO value if corresponding H:C:T:L entry
is empty.

Removing this print 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.
