Xin LI 64e0f48e7c Add a bandaid for a long-standing race condition during route entry 
un-expiring.

The previous version of code have no locking when testing rt_refcnt.
The result of the lack of locking may result in a condition where
a routing entry have a reference count but at the same time have
RTPRF_OURS bit set and an expiration timer.  These would eventually
lead to a panic:

	panic: rtqkill route really not free

When the system have ICMP redirects accepted from local gateway
in a moderate frequency, for instance.

Commit this workaround for now until we have some better solution.
