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.
