Doh.  This should of course be VTOUNION(un2->un_dirvp), and with it
that way, instead of spinning forever, I get a quick crash from a null
pointer dereference.  Can't walk up via un_pvp either, it seems.

I believe this is the right algorithm to fix this problem, but how do
I safely walk up and test at each level?
