qcacld-3.0: Fix OOB write in wma_extscan_change_results_event_handler
The routine wma_extscan_change_results_event_handler sends the ext scan
results to upper layers. This contains the bssid info, rssi values of
different APs that are scanner. If the num_rssi_samples is negative or
greater than UINT32_MAX,then an OOB write could happen.
Add check to ensure rssi_num is not negative or exceeds UINT32_MAX.
Also make sure the numap value is not negative.
