mac80211: set only VO as a U-APSD enabled AC
commit d6a4ed6fe0a0d4790941e7f13e56630b8b9b053d upstream.
Some APs experience problems when working with U-APSD. Decrease the
probability of that happening by using legacy mode for all ACs but VO.
The AP that caused us troubles was a Cisco 4410N. It ignores our
setting, and always treats non-VO ACs as legacy.
