ath9k_htc: Fix beaconing in IBSS mode

The current way of managing beaconing in ad-hoc
mode has a subtle race - the beacon obtained from mac80211
is freed in the SWBA handler rather than the TX
completion routine. But transmission of beacons goes
through the normal SKB queue maintained in hif_usb,
leading to a situation where __skb_dequeue() in the TX
completion handler goes kaput.

Fix this by simply getting a beacon from mac80211 for
every SWBA and free it in its completion routine.
