From: Xinming Hu <huxm@xxxxxxxxxxx> If tx_pkts_queued is increased for tx paused receive address, tx process will be triggered for this packet. But since RA list was tx paused, there will be an infinite loop in mwifiex_wmm_process_tx waiting for the event(tx pause, tdls cs) to cancel tx pause. This will be an dead loop, since main_process was locked at this time, there will be no opportunity to process event. So do not increase tx_pkts_queued if receive address tx paused, this will be restored RA list is unpaused.
