[IPV4]: Convert do_gettimeofday() to getnstimeofday().
What do_gettimeofday() does is to call getnstimeofday() and to convert the result from timespec{} to timeval{}. After that, these callers convert the result again to msec. Use getnstimeofday() and convert the units at once. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>
