Subject: [PATCH] librdmacm: only allocate qp in rdma_create_ep if qp_attr
 provided

The comments and documentation for rdma_create_ep indicate that
it will only allocate a QP if initial QP attributes are provided.
However, the code always attempts to create a QP off an
active rdma_cm_id endpoint.

By _not_ allocating the QP, a user can first determine
what RDMA device an rdma_cm_id was associated with (returned from
rdma_create_ep).  The user can then call rdma_create_qp to
allocate a QP referencing an existing CQ, SRQ, or PD.
