Clear ro->ro_rt just after RTFREE().
Pleases let me make sure that no one touch the invalid ro_rt pointer,
after splx(s) and before next ro_rt initialization.
Though usually this seems to be already called at splnet,
I still sometime experience kernel crash at rtfree() in my
INET6 enabled environment where IPv6 connection is frequently used.
(Off-course, it might be just due to another bug.)
