Revert "mac80211: disable uAPSD if all ACs are under ACM" 

commit bb512ad0732232f1d2693bb68f31a76bed8f22ae upstream.

This reverts commit 24aa11ab8a.

That commit was wrong since it uses data that hasn't even been set
up yet, but might be a hold-over from a previous connection.

Additionally, it seems like a driver-specific workaround that
shouldn't have been in mac80211 to start with.
