NFSROOT is broken after r196714

[Li, Qing]

Do you know what IP address nfsclient/nfs_vfsops.c:466 is trying to 
insert and do you have an output of the "ifconfig" and route 
table you can send to me privately?

At the moment I am suspecting r196714 uncovered an issue that has
always been there. But that's an assumption at the moment.

Thanks,
