Title
Bluetooth: hci_conn: Fix memory leaks
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: Fix memory leaks
When hci_cmd_sync_queue() failed in hci_le_terminate_big() or
hci_le_big_terminate(), the memory pointed by variable d is not freed,
which will cause memory leak. Add release process to error path.
