v8.2.0 crashes with null pointer for nifa_p with DEBUG=true

[theweathermanda]

I'm running v8.2.0 compiled on Derecho as follows:
make nvhpc CORE=atmosphere AUTOCLEAN=true PRECISION=single DEBUG=true OPENACC=true >& compile.log

With DEBUG=true, I receive the following error at runtime:
0: Null pointer for nifa_p (mpas_atmphys_driver_pbl.F: 904)

which is associated with call mynn_bl_driver, wherein nifa is declared an optional argument.

I think PR #1215 may address this issue.
