Commit 3a25a8c8 (mac80211: add improved HW queue control) introduced a
bug when running in AP mode without the IEEE80211_HW_QUEUE_CONTROL
flag set. The ieee80211_check_queues() function always returns
-EINVAL, preventing AP mode from starting. To fix this, check whether
this flag is set before checking if cab_queue is set properly.
