[BUG/ISSUE] Number of ND64 tracers gets set to zero in input_mod.F

[yantosca]

Describe the bug
The ND64 bpch radiative flux diagnostics are not printed out, even when ND64 is turned on in input.geos.

To Reproduce

1. Create a geosfp_4x5_standard run dir.
2. make -j8 all
3. make -j8 run

Expected behavior
The ND64 tracers should be saved to the bpch file, and metadata printed to tracerinfo.dat.

Required information

• GEOS-Chem 12.6.0, in bugfix/RRTMG branch
• gfortran 9.2.0 via Spack
• netcdf 4.7.0
• netcdf-fortran 4.4.5
