`sendcounts`, `sdispls`, and `sendtype(s)` must be ignored
if `MPI_IN_PLACE` is specified for `sendbuf`.
This commit makes the param check code same as the blocking
`ALLTOALL{V|W}` function.
`MPI_IN_PLACE` support for `MPI_ALLTOALLW` and `MPI_EXSCAN` was added in MPI-2.2 but it was missed in OMPI Fortran binding code.

@kawashima-fj do you want to PR this to v1.10.3 and/or v2.0.0? (I would assume 2.0.x at a minimum) |
