    ada: Cleanup code for warnings about unreferenced formal parameters
    
    Cleanup related to new checks for unset references.
    
    gcc/ada/
    
            * sem_warn.adb (Check_References): Remove redundant guard, as it
            is implied by a preceding call to Referenced_Check_Spec.
