When USES_RSS is enabled, last_rx becomes zero in first few
minutes after sta connection in sta_get_last_rx_stats. This
leads to inactive time showing current jiffies in msecs.
Station 8c:fd:f0:02:10:dd (on wlan0)
inactive time: 4294701656 ms
.
.
connected time: 2 seconds
Fix this by avoid overwriting last_rx with percpu_stat's last_rx
if it is zero.
