Bluetooth: Check that bind() bdaddr type matches connect()
If a socket was bound to an address type other than BR/EDR (such as LE) we should reject trying to connect it to a BR/EDR address. The same applies for binding to BR/EDR and trying to connect to non-BR/EDR. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
