This is probably another driver bug. Try kldunloading and kldloading your wlan driver to see if that works, and/or start stripping your kernel of unnecessary options until you find the magic formula for what works, and just apply that to rc.suspend // rc.resume and file a PR for the driver bug if there isn't one already.
