atheroswifi driver causes vm address fault at startup

[v.vill]

After upgrading to hrev52099, thus taking advantage of the updated atheroswifi driver (see #14249), the boot sequence ends in KDL with the following messages:

start_wlan: wlan started.

I’m running Haiku x86_64 (EFI boot) with an AR9565 chipset wifi chip (vendor/device: 168c/036).
