nfsd: update mtime/ctime on COPY in presence of delegated attributes

Browse source

When delegated attributes are given on open, the file is opened with
NOCMTIME and modifying operations do not update mtime/ctime as to not get
out-of-sync with the client's delegated view. However, for COPY operation,
the server should update its view of mtime/ctime and reflect that in any
GETATTR queries.

Fixes: e5e9b24ab8 ("nfsd: freeze c/mtime updates with outstanding WRITE_ATTRS delegation")
