[IPV4]: Clean the ip_sockglue.c from some ugly ifdefs
The #idfed CONFIG_IP_MROUTE is sometimes places inside the if-s, which looks completely bad. Similar ifdefs inside the functions looks a bit better, but they are also not recommended to be used. Provide an ifdef-ed ip_mroute_opt() helper to cleanup the code. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
