wifi: mac80211: use jiffies_delta_to_msecs() for sta_info inactive times

Inactive times of around 0xffffffff milliseconds have been observed on
an ath9k device on ARM.  This is likely due to a memory ordering race in
the jiffies_to_msecs(jiffies - last_active()) calculation causing an
overflow when the observed jiffies is below ieee80211_sta_last_active().

Use jiffies_delta_to_msecs() instead to avoid this problem.
