ipv6: exthdrs: use swap macro in ipv6_dest_hao
make use of the swap macro and remove unnecessary variable tmp_addr. 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>
