REST_OPTION=nsteps not working correctly

[jedwards4b]

I don't believe that the mediator is correctly triggering RESTART writes. In the following case I get restart files for all components except rof and cpl.

create_newcase --case f.cam6_3_144.ne30.datest --res ne30pg3_ne30pg3_mg17 --compset FMTHIST --run-unsupported
./xmlchange REST_OPTION=nsteps
./xmlchange REST_N=12
./xmlchange STOP_OPTION=nsteps 
./xmlchange STOP_N=24 
./xmlchange DOUT_S=FALSE

I think that the issue is in the way that the restart timestep is calculated, from the mediator log I see:
(med_phases_restart_alarm_init) restart clock timestep = 10800
Which I believe is based on the ROF_NCPL=8. We don't see this issue in the tests because the tests reset
ROF_NCPL=48 prior to running to allow the test to have a shorter overall length.
