mac80211: fix station inactive_time shortly after boot

In the first 5 minutes after boot (time of INITIAL_JIFFIES),
ieee80211_sta_last_active() returns zero if last_ack is zero. This
leads to "inactive time" showing jiffies_to_msecs(jiffies).

 # iw wlan0 station get fc:ec:da:64:a6:dd
 Station fc:ec:da:64:a6:dd (on wlan0)
inactive time: 4294894049 ms
.
.
connected time: 70 seconds

Fix by returning last_rx if last_ack == 0.
