Rainer Keller b0df55d53b - For MPI_Probe/MPI_Iprobe, we should not have a
PERUSE_COMM_REQ_ACTIVATE event.
   Therefore move the PERUSE_TRACE_COMM_EVENT for this event from
   MCA_PML_BASE_SEND_REQUEST_INIT / MCA_PML_BASE_RECV_REQUEST_INIT
   to the proper places into pml_ob1_isend.c / pml_ob1_irecv.c right
   after the MCA_PML_OB1_SEND_REQUEST_INIT /
   MCA_PML_OB1_RECV_REQUEST_INIT.

This commit was SVN r15945.
