AP: Fix inactivity STA timer trigger for driver offload case

Some non-mac80211 drivers, such as ath6kl, support STA inactivity timer
in firmware and may not provide connected stations' idle time to the
userspace. If the driver indicates support for offloaded operation, do
not start the inactivity timer in the hostapd.
