qcacmn: Update the vdev_id in the vdev_chain_rssi stats
In tgt layer, rssi_stats are copied by comparing the vdev id
filled in the target layer and last reqested stats vdev id.
But in target layer api, target_if_cp_stats_extract_vdev_chain_rssi_stats
vdev id is not filled and that can lead to wrong stats in the upper
layers.
Update vdev id in the rssi stats.
