mac80211: Move up init of TXQs
On init, ieee80211_if_add() dumps the interface. Since that now includes a
dump of the TXQ state, we need to initialise that before the dump happens.
So move up the TXQ initialisation to to before the call to
ieee80211_if_add().

Fixes: 52539ca89f36 ("cfg80211: Expose TXQ stats and parameters to userspace")
