land_null errors out with nvidia compiler nvhpc/22.7 on c5 character buffer is too small; increase length: netcdf_read_data_0d: file:INPUT/grid_spec.nc- variable:lnd_mosaic

Describe the bug
Regression test fails with the latest nvidia compiler on c5 :

FATAL from PE 7: character buffer is too small; increase length: netcdf_read_data_0d: file:INPUT/grid_spec.nc- variable:lnd_mosaic

This is under FMS2023.02 release. In previous releases I could bypass the error by reverting land_null to pre-mosaic2 version. But older tags of land_null do not compile with FMS2023.02

To Reproduce
frerun -s -r basic -u --no-transfer -x /ncrc/home2/Niki.Zadeh/frerts/fre/FMS2023.02_mom6_20230828/_0/OM4_extra.xml.20230810143846 -p ncrc5.pgi227 -t prod MOM6_GOLD_SIS2_generics

Expected behavior
Not to crash.

System Environment
ncrc5 nvhpc22.7

Additional context
None of the regression tests that use land_null run any more with nvidia compiler.

@nikizadehgfdl - do you see this with the later versions we have installed on the dev box? If not, we can use this to push ORNL to upgrade the installations on gaea.

This particular error does not happen with nvhpc/23.7 on the amdbox.
However the ocean-ice model crashes without any hints somewhere else in land_null. Adding print statements indicate the crash happens in the calls to get_grid_cell_area . The ocean-ice models can be run without these calls and by just setting frac=1.0 instead.
But that is all perhaps unrelated to this issue. Closing.

Just for future reference, here's the land_null PR that allows ocean-ice models to run with nvhpc/23.7 under FMS2023.03
