ath6kl: Fix invalid pointer access on fuzz testing with AP mode
In our Fuz testing, reference client corrupts the dest mac to "00:00:00:00:00:00" in the WPA2 handshake no 2. During driver init the sta_list entries mac addresses are by default "00:00:00:00:00:00". Driver returns an invalid pointer (conn) and the drver shall crash, if rxtids (aggr_conn) skb queues are accessed, since they would not be initialized.
