when dt/dtrt_ch is not an integer

[jmccreight]

I dont know if this is important to flag or not.
I was running LSM DT = 900 sec and DTRT_CH = 120 sec. I'm not sure what the ouput files were really representing (I assume the channel state 1 minute later was being written to the file, because I didnt notice any correction of DTRT_CH, but I didnt look very hard).

For my branch I added this to Data_Rec/module_namelist.F

if(DT/nlst%DTRT_CH .ne. real(int(DT) / int(DTRT_CH)) ) &
     call hydro_stop("driveChannelRouting: DT not a multiple of DTRT_CH")

If you like it add it to master, otherwise, ignore it and close issue.

The WRF-Hydro is driven by Land surface model. It is incorrect if the
routing time step is bigger than land surface model.

For coupled with WRF, we have a check and automatic set the routing to
be <= land surface time step. In offline, we do not have this setting.
However, in future, we need to add functions for checking the namelist
parameters, just as what WRF did now.

|Forget to mention, you can put this check into a separate function,
just like WRF model. We will add others to the same function in the future.
