Bug in writing restart file times

[julietbravo]

With the MicroHH2 master I get:

Saving "time.0010800" ... OK
Saving "qt.0010801" ... OK
Saving "thl.0010801" ... OK

This is the relevant piece of code:

                // Save the data for restarts.
                if (timeloop->do_save())
                {
                    #ifdef USECUDA
                    if (!cpu_up_to_date)
                    {
                        #pragma omp taskwait
                        cpu_up_to_date = true;
                        fields  ->backward_device();
                        boundary->backward_device();
                        thermo  ->backward_device();
                    }
                    #endif
                    // Save data to disk.
                    #pragma omp task default(shared)
                    {
                        timeloop->save(timeloop->get_iotime());
                        fields  ->save(timeloop->get_iotime());
                    }
                }

Not sure what the best solution would be; save the iotime inside the block with pragma omp?taskwait?
