One of the changes in iwlwifi caused the hwscan to start locking the system and at the time it was easier to comment it out and focus on other issues (rate scaling was broken as well)  

When the hw scanning does work, its returns scan results a lot faster to the user without as much processing overhead, so we'll definitely want to switch back to using the hwscan for iwlwifi.
