mac80211: drop check for DONT_REORDER in __ieee80211_select_queue
When __ieee80211_select_queue is called, skb->cb has not been cleared yet,
which means that info->control.flags can contain garbage.
In some cases this leads to IEEE80211_TX_CTRL_DONT_REORDER being set, causing
packets marked for other queues to randomly end up in BE instead.
This flag only needs to be checked in ieee80211_select_queue_80211, since
the radiotap parser is the only piece of code that sets it
Fixes: 66d06c84730c ("mac80211: adhere to Tx control flag that prevents frame reordering")
