ath10k: deinit wow config in driver unload

Browse source 
The mac80211 support user configured wowlan enable/disable
feature using wlan utils, If the wowlan feature is not enabled
by user the mac80211 subsystem fallback to core stop instead
of wow suspend during system suspend even the wlan firmware
support wowlan feature.

So in driver load init wow and set the wlan device as a wakeup
capable device and deinit wow in driver unload.
