Missing file and compilation error in EAMxx

[odiazib]

A couple of issues when compiling EMAxx in my linux machine:

• Missing file:

The file homme_mam4xx_ne4_init.nc does not exit in https://portal.nersc.gov/project/e3sm/inputdata/atm/scream/init.

To fix this issue:
I got a copy of this file from @jeff-cohere.

• Compilation error due to mpif90

I had the following compilation error:

1947 |        call MPI_ALLREDUCE(lvec,gvec,gsize,MPI_REAL8,reduce_type,comm,ierr)
      |                          1
......
 2004 |        call MPI_ALLREDUCE(lvec,gvec,gsize,MPI_REAL8,reduce_type,comm,ierr)
      |                          2
Error: Rank mismatch between actual argument at (1) and actual argument at (2) (rank-1 and scalar)

To fix this issue, I added the following cmake command.

-D CMAKE_Fortran_FLAGS="-fallow-argument-mismatch -fallow-invalid-boz" \

This was recommended here:

Thanks, Oscar. Others: the missing file is only needed when we configure EAMxx to build with mam4xx, and we'll get it (or its successor) uploaded to the data server when the time comes.
