SF: need to sync the stream before MPI send even when there is nothing to send but has something to receive

There might be pending gpu operations on the receive buffer. Without synchronization, say we proceed to MPI_Waitall(). MPI might stage on host and do a H2D copy on an internal stream on the receive side. Previous gpu operations COULD happen after the H2D copy, causing a write-after-write reorder violation!
