mpi/fortran: Fix valgrind warnings for type create

Valgrind warns that *newtype is uninitialized when calling from
Fortran as e.g.
    use mpi
    integer :: t, err
    call MPI_Type_create_f90_integer(5, t, err)

Since newtype is intent(out), this should not happen. There is
no reason to convert the type using PMPI_Type_f2c, only to over-
write it immediately afterwards. The other type_create_* functions
did not convert newtype.

The valgrind warnings:
