    Fix uninitialised read in OperationDetail::set_status()
    
    Setting the status and controlling the timing of operation details
    initialised with OperationDetail(desc, status, font) uses a conditional
    branch depending on the uninitialised variable this->status.
    
    valgrind:
    ==28957== Conditional jump or move depends on uninitialised value(s)
    ==28957==    at 0x80E4287:
    GParted::OperationDetail::set_status(GParted::OperationDetailStatus)
    (OperationDetail.cc:77)
    
    OperationalDetail.cc:
       75  void OperationDetail::set_status( OperationDetailStatus status )
       76  {
    >> 77          if ( this ->status != STATUS_ERROR )
       78          {
       79                  switch ( status )
