Fix unreachable inner if condition

[baderouaich]

The outer condition checks if op is one of "sclpsv", "sclpsp" or "sclpsd" where the inner condition checks against "sclsv" and "sclsp".

Enums will be a great choice here, as the code grows you have to keep track of the exact string option. However, you may also consider using a static analysis tool such as Cppcheck to detect issues like this. You might also integrate it into a CI workflow for automated checks.

Have a great day!
