[PATCH] mac80211: Always show airtime debugfs file when TXQs are enabled

[Toke Høiland-Jørgensen]

The AQL statistics are displayed in the 'airtime' station debugfs file, but
that file was only shown if a driver has enabled the airtime fairness
feature flag. Since AQL can be enabled without airtime fairness, let's
expose the airtime file whenever TXQs are enabled, so the AQL data can be
read.

With the change to an NL80211_EXT_FEATURE for AQL, this is no longer
needed, so please drop this patch.
