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.
