scsi: target: fix unsigned comparision with less than zero
Currently an error return is being assigned to an unsigned size_t varianle
and then checked if the result is less than zero which will always be
false. Fix this by making ret ssize_t rather than a size_t.
Fixes: 0322913cab79 ("scsi: target: Add device product id and revision configfs attributes")
