This fixes the cause of warning messages in the log files when the rental discount in the circulation rules has a blank value.
Before this fix, multiple warning messages "[2021/07/28 12:11:25] [WARN] Argument "" isn't numeric in subtraction (-) at /kohadevbox/koha/C4/Circulation.pm line 3385." appeared in the log files. These warnings occurred for items checked out where they had rental charges and the rental discount value in the circulation rules was blank.
