Rate control statistic is flushed whenever the mesh beacon is received. This may not optimizes the performance of rate control algorithm. This patch ensures that we return early from mesh_peer_init if the plink_state is ESTAB. Thus, avoid calling the rate_control_rate_init again for established mesh STA.
