Bluetooth: Reject SCO when hci connection timeouts
This patch sends Reject Synchronous Connection Request Command when hci_conn_timeout is triggered, and the SCO connection is in BT_CONNECT2 state. It prevents inconsistency if the remote host doesn't implement properly the timeout for the connection request, and it removes the connection reference left when the socket is closed for incoming SCO connections.
