The RDMA CM fail calls to set REUSEADDR on an rdma_cm_id if it is not in the idle state. As a result, this causes a failure in NetPipe when run with socket calls intercepted by rsockets. Fix this by returning success when REUSEADDR is set on an rsocket that has already been connected. When running over IB, REUSEADDR is not necessary, since the TCP/IP addresses are mapped.
