Subject: [PATCH] scsi/dev: print an error when cannot find bdev with specified
 name

When trying to create a scsi dev with inexistent
lun (bdev name), the scsi_dev_construct would
just return a NULL without printing any error.
We should probably return an error code of some
kind, but for now let's just print an extra
message.
