qcacld-3.0: Fix rx rate report when throuthput is high
When rx throughput is relatively high, driver will not refill rx
rates info. This has been done in wlan_hdd_get_peer_rx_rate_stats()
so that wlan_hdd_refill_actual_rate() do not need to consider this
condition. Otherwise, we will fail to report rates info to kernel.
