pml/ob1: add missing ompi_request_wait_completion for buffered sends

This commit adds a call to ompi_request_wait_completion for buffered sends. Without this line it is possible to get into a state where the data is never sent. Fixes open-mpi#1185 (cherry picked from commit open-mpi/ompi@f68c315) Signed-off-by: Nathan Hjelm <hjelmn@lanl.gov>
