RACK: Fix re-transmitting the segment twice when entering recovery.
TestRACKWithDuplicateACK is flaky as the reorder window can expire before receiving three duplicate ACKs which will result in sending the first unacknowledged segment twice: when reorder timer expired and again after receiving the third duplicate ACK. This CL will fix this behavior and will not resend the segment again if it was already re-transmittted when reorder timer expired. Update the TestRACKWithDuplicateACK to test that the first segment is considered as lost and is re-transmitted. PiperOrigin-RevId: 356855168
