Bluetooth: Don't send RFC for Basic Mode if only it is supported
If the remote side doesn't support Enhanced Retransmission Mode neither Streaming Mode, we shall not send the RFC option. Some devices that only supports Basic Mode do not understanding the RFC option. This patch fixes the regression found with these devices. Signed-off-by: Gustavo F.
