Bluetooth: Fix race condition with L2CAP information request
When two L2CAP connections are requested quickly after the ACL link has been established there exists a window for a race condition where a connection request is sent before the information response has been received. Any connection request should only be sent after an exchange of the extended features mask has been finished. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
