net: dccp: ccids: lib: packet_history: use swap macro in tfrc_rx_hist_swap
Make use of the swap macro and remove unnecessary variable tmp. This makes the code easier to read and maintain. This code was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R. Silva <garsilva@embeddedor.com> Signed-off-by: David S. Miller <davem@davemloft.net>
