Gilles Gouaillardet 60e91e890a coll/base: give a boost to ompi_coll_base_sendrecv_nonzero_actual()
Based on current implementation it is faster to use a blocking
send than the non-blocking version. Switch the exchange function
used in the barrier to use the blocking version combined with
the non-blocking version of the receive.

This is similar to open-mpi/ompi@223d75595d
