qcacld-3.0: update the adapter->rssi from fw

Browse source 
Currently, sta's adapter.rssi does not reset when disconnect
with the previous ap and for new connection there might be no
valid rssi so it will get 0 when hdd_get_station_statistics_cb
or hdd_get_rssi_cb is invoking. Then it uses the previous ap's
rssi for the new conneciton.

Per the code logic, it is ok to set adapter.rssi with 0 value.
Because it invokes hdd_get_rssi_snr_by_bssid to get the
rssi & snr when issue happens.
