iwlagn: properly wait for PAN disable
Previously I hacked this with an msleep(300)
which was fine since we never had longer PAN
time slots, but now that we will have them I
need to fix that. Use the new notification
wait support to properly wait for the WIPAN
deactivation complete signal from the ucode.
