    Remove (N/A) from comment in FileSystem::rm_temp_dir()
    
    Extra hint of warning status being represented by enumeration constant
    STATUS_N_A is no longer needed since commit:
        8c5c13d613474d3853d6071c5be8055d49bef5aa
        Rename OperationDetailStatus STATUS_N_A to STATUS_WARNING
