Rainer Keller bb2d0b45cd - Coverity CID37: if requests == NULL, do not deref requests[i] for
multi-completion calls. Therefore reorder tests where appropriate.
 - Always check for NULL-pointers (flag, index, completed) (yes, we
   use them in the underlying ompi_request_* functions.
 - Break early, if a NULL-request is found
