lor in in.c and if_ural.c

Hi,

I got this lock order reversal on 7.0-CURRENT today:

lock order reversal: (Giant after non-sleepable)
 1st 0xc06aaea0 in_multi_mtx (in_multi_mtx) _at_ /usr/src/sys/netinet/in.c:964

Looks related to http://sources.zabbadoz.net/freebsd/lor.html#157, but
with a different driver?
