Fix "net" command on kernel configured with CONFIG_IPV6=m 

On a kernel configured with CONFIG_IPV6=m, struct inet6_ifaddr is not
defined in kernel.  Without the patch, the "net" command fails with the
following error.

  net: invalid structure member offset: inet6_ifaddr_if_next
       FILE: net.c  LINE: 1017  FUNCTION: get_device_ip6_address()
