Subject: mac80211: unconditionally start new netdev queues with iTXQ support

From: Johannes Berg <[email protected]>

commit 7d65f82954dadbbe7b6e1aec7e07ad17bc6d958b upstream.

When internal mac80211 TXQs aren't supported, netdev queues must always started out started even when driver queues are stopped while the interface is added. This is necessary because with the internal TXQ support netdev queues are never stopped and packet scheduling/dropping is done in mac80211.
