Don't you get a REJ now when there is no one listening on a service ID
requested ?

-22 is EINVAL. In terms of ib_send_cm_req, it is returned for a number
of cases:
1. peer to peer connection is requested
2. No primary path is supplied
3. QP is not RC or UC
4. private data is supplied and length > 92
5. alternate path supplied and PKEY or MTU does not match primary path
6. connection state is not IDLE
7. Primary or alternate path SGID or PKey does not match those of port
