rpc: fix a routine to destory RDMA qp(queue-pair)
Problem: If an error has occured with rdma_create_id() in gf_rdma_connect(),
process will jump to the 'unlock' label and then call gf_rdma_teardown()
which call __gf_rdma_teardown().
Presently, __gf_rdma_teardown() checks InifiniBand QP with peer->cm_id->qp!
Unfortunately, cm_id is not allocated and will be crushed in this situation :)
Solution: If 'this->private->peer->cm_id' member is null, do not check
'this->private->peer->cm_id->qp'.
