NFS: Fix attribute delegation behaviour on exclusive create

Browse Source 
When the client does an exclusive create and the server decides to store
the verifier in the timestamps, a SETATTR is subsequently sent to fix up
those timestamps. When that is the case, suppress the exceptions for
attribute delegations in nfs4_bitmap_copy_adjust().

Fixes: 32215c1f89 ("NFSv4: Don't request atime/mtime/size if they are delegated to us")
