wifi: mac80211: cleanup airtime arithmetic with ieee80211_sta_keep_active()
Prefer native jiffies-wide 'unsigned long' for the 'last_active' field of
'struct airtime_info' and introduce 'ieee80211_sta_keep_active()' for airtime
check in 'ieee80211_txq_keep_active()' and 'ieee80211_sta_register_airtime()'.
