mac80211: Fix condition validating WMM IE
[ Upstream commit 911a26484c33e10de6237228ca1d7293548e9f49 ]
Commit c470bdc1aaf3 ("mac80211: don't WARN on bad WMM parameters from
buggy APs") handled cases where an AP reports a zeroed WMM
IE. However, the condition that checks the validity accessed the wrong
index in the ieee80211_tx_queue_params array, thus wrongly deducing
that the parameters are invalid. Fix it.
