Well after the removal of DRIVER_REQUIRE_SCHEDULED I only have 1
workqueue structure left: Updating beacons.
During the update it needs to iterate through all interfaces using
ieee80211_iterate_active_interfaces_atomic(), during the actual update
a mutex is required because USB device access is required. And not in the least
the function is called by the set_tim() callback function.
