HDMI: Retry one time to send <Request Active Source>

When TV is finishing the logical address allocation it will send a
<Request Active Source> message. This message is often ignored by
connected devices because they are still finishing their address
allocation. In ag/25261376 we introduced that if the <Request AS>
message is not answered within 2s, the TV will broadcast <Active
Source>.
With this CL we retry sending <Request Active Source> one more time, to
be more confident there is no device answering this message.
