RDMA/nes: Use atomic counters for CM listener create and destroy
After running long iterative MPI tests, sometimes ethtool reports a "CM Destroy Listener" count more than the "CM Create Listener" count. This inconsistency is fixed by making counter variables atomic. Signed-off-by: Faisal Latif <faisal.latif@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
