nfsd: find_cpntf_state cleanup
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. Signed-off-by: J.
