[PATCH v2 13/16] ratp: send initial data in behaviour B if any pending

[Aleksander Morgado]

And also, use ratp_send_ack() instead of manually constructing an ACK
if no data is pending to be sent.

The current barebox implementation doesn't allow any queueing of data
until the connection is established, so this is probably not a case
that would get run anyway.
