qcacld-3.0: Fix Rx throughput level calculation

Browse source 
Currently the rx throughput level is getting set to TP_NONE immediately
after it goes high. This will send incorrect values for
tcp_adv_win_scaling to cnss-daemon.
Fix the RX throuhgput level by making next_rx_level a static variable.
Now if next_rx_level is calculated to be HIGH, it will stay HIGH until
RX throughput falls below the threshold
