NFS: fix RENAME attr in presence of directory delegations

Browse Source 
Since commit 6f9bda2337 ("NFS: Fix directory delegation
verifier checks") xfstest generic/309 is failing because after
the rename (mv) operation, client's mtime/ctime is the same.
Update the delegated mtime when directory delegations are
present in rename.
