Handle OMPI_REQUEST_NOOP in MPI_Startall rather than PML
cmr=v1.8.2:reviewer=bosilca:ticket=4764
This commit was SVN r32213.
The following Trac tickets were found above:
Ticket 4764 --> https://svn.open-mpi.org/trac/ompi/ticket/4764
This corner case is now handled in the pml so the same code
is invoked for both MPI_Start and MPI_Startall.
This also correctly report an error if MPI_Startall is invoked twice
on a MPI_PROC_NULL persistent request.
