I was able to reproduce this with -current, but looking at the code I
don't understand how that vfs op is getting nulled out. It should be set
to the default operation which just return EOPNOTSUPP.  I guess some
KASSERTs are in order.

The function itself hasn't changed materially in months, so its hard to
tell when this crept in.  Out of curiousity, do you have a -stable box
around, and can you reproduce on that?
