From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>
This fixes using wrong QoS settings when attempting to send frames while
acting as peripheral since the QoS settings in use are stored in
hconn->iso_qos not in sk->qos, this is actually properly handled on
getsockopt(BT_ISO_QOS) but not on iso_send_frame.
Fixes: ccf74f2390d60 ("Bluetooth: Add BTPROTO_ISO socket type")
