From: "J. Bruce Fields" <bfields@xxxxxxxxxx>
I think this unusual use of struct compound_state could cause confusion.
It's not that much more complicated just to open-code this stateid
lookup.
The only change in behavior should be a different error return in the
case the copy is using a source stateid that is a revoked delegation,
but I doubt that matters.
