From: Johannes Berg <johannes.berg@intel.com>

The original patch didn't copy the ieee80211_is_data() condition
because on most drivers the management frames don't go through
this path. However, they do on iwlwifi/mvm, so we do need to keep
the condition here.

Fixes: ce2e1ca70307 ("mac80211: Check port authorization in the ieee80211_tx_dequeue() case")

Dave, can you please apply this directly?
