Subject: [PATCH 12/26 v3] rdma/cm: Add support for AF_IB to
 cma_get_service_id

cma_get_service_id forms the service ID based on the port space
and port number of the rdma_cm_id.  Extend the call to support
AF_IB, which contains the service ID directly.  This will
be needed to support any arbitrary SID.
