media: cec: fix the Signal Free Time calculation
The calculation of the Signal Free Time in the framework was not
correct. If a message was received, then the next transmit should be
considered a New Initiator and use a shorter SFT value.
This was not done with the result that if both sides where continually
sending messages, they both could use the same SFT value and one side
could deny the other side access to the bus.
Note that this fix does not take the corner case into account where
a receive is in progress when you call adap_transmit.
