    media: cec: core: don't set last_initiator if tx in progress
    
    [ Upstream commit 73af6c7511038249cad3d5f3b44bf8d78ac0f499 ]
    
    When a message was received the last_initiator is set to 0xff.
    This will force the signal free time for the next transmit
    to that for a new initiator. However, if a new transmit is
    already in progress, then don't set last_initiator, since
    that's the initiator of the current transmit. Overwriting
    this would cause the signal free time of a following transmit
    to be that of the new initiator instead of a next transmit.
