iwlwifi: optimize power saving
In hostap AP mode, every time the client sends the AP
a packet the STA_NOTIFY_AWAKE code is sent from mac80211.
This results in a command being sent to the uCode even if
the client was not asleep.
The following simple patch has fixed the issue for me without any
degradation that I can find.
