mpi.h: file errhandeler typedef: use new form of name

The old/deprecated form of the file errhandler typedef used "fn" as a
suffix.  The new form uses the name "function".

The MPI API typedef name has already been updated to use "function";
this commit updates the internal Open MPI typedef to use the name
"function" to match the MPI API name and avoid confusion.
