incorrect namelist options for nonydro tests

[xylar]

I'm seeing:

config_use_constant_forced_pgf is not in the namelist and replacements will not be used

when I set up the ocean/nonhydro/solitary_wave and ocean/nonhydro/stratified_seiche tests using https://github.com/scalandr/E3SM/tree/ocean/nonhydro

@scalandr, can you take a look at this an see if a bug fix is needed?

Hi @xylar, the only thing to be done is to get rid of config_use_constant_forced_pgf = .false. in namelist.nonhydro for both the solitary wave and stratified seiche test. That is an old flag that is not present anymore in the current nonhydro code. Do you want me to open a PR with this fix?

[xylar]

@scalandr, yes, no rush but if you can open a PR, that would be great!
